1. Bitcoin and Ethereum are hard currencies in the blockchain world. If new investors don't understand which digital assets to buy, it is recommended to choose BTC and ETH.

2. There are many categories of digital currencies, including: currency type (BTC), platform type (ETH), application type (SC), stable type (USDT), and dividend type (repurchase BNB). Digital currencies have various properties. New investors should only distinguish between valuable coins and worthless coins; valuable coins can be held long-term, while worthless coins should not be touched even if they increase by a thousand times!

3. Legal currency purchasing channels include: over-the-counter trading platforms and private over-the-counter transactions. Over-the-counter trading platforms generally support multiple assets such as BTC/ETH/EOS, while private over-the-counter transactions depend on the scale, with most only supporting BTC and ETH hard currencies. It is advisable to avoid private transactions without guarantees, as it is difficult to recover funds once scammed.

4. Conventional trading platforms: bitfinex, bittrex, binance, okex, Huobi, etc. Bitfinex has the most diverse gameplay, Bittrex has the largest trading volume, and Binance has the best experience; the combination of the three can basically meet all the needs of ordinary users.

5. Common wallets: for Ethereum, Imtoken is recommended; for Bitcoin, Bitpie is recommended. Be sure to keep your private key and mnemonic phrase safe! Once forgotten, assets will be wiped out.

6. Important digital assets other than air coins should not be kept on websites; they must be stored in secure wallets. Most websites do not guarantee 100% security, and theft, insider theft, or exit scams happen frequently!

7. Due to its financial nature, the field of cryptocurrency is a hotspot for hackers. When registering on exchanges, be sure to take protective measures and enable Google two-factor authentication! Do not use the same account and password across different websites; if there is a data breach, all will be stolen.

8. The operation process for cryptocurrency trading is: fiat currency → Bitcoin/Ethereum → blockchain project tokens → Bitcoin/Ethereum → fiat currency.

9. The full name of ICO is: Initial Coin Offering. Essentially, it allows smaller companies to publicly raise funds through their own issued virtual currency at the beginning of their establishment, similar to a stock market IPO (Initial Public Offering).

10. Participation in ICOs has time and amount restrictions. Generally speaking, the earlier the investment, the higher the return, but some projects cannot be bought just by having money. For example, airdrop projects (except for a few normal projects for market promotion, most are worthless coins; be sure to avoid using the same account password as your regular ones), and there are also projects that do not lack funds like rsk.

11. Regarding private placements, they usually promise high returns. In fact, most unofficial direct investments or verified ones are scams. Do not believe in proxy investments; when they run off with the money, where will you go to find them? For proxy investments, make sure they have a history of private placements, and this private placement can be verified through official institutions!

12. The investment risks in Western Europe are extremely high, and ordinary people can easily be swept away by high returns. It is not recommended for ordinary people to participate excessively: first, ordinary people do not have the ability to discern the authenticity of projects; second, there is no corresponding regulation, and scammers come in many forms; apart from oneself, there is no one to rely on.

13. The operation process in Western Europe is: fiat currency → Bitcoin/Ethereum → official account → distribute tokens → Bitcoin/Ethereum → fiat currency.

14. Trading cryptocurrencies is different from trading stocks; do not approach it with a stock trading mindset. Daily fluctuations of 50% up and down in cryptocurrencies happen every day, and multiplying dozens or hundreds of times is also very common. As the saying goes: one day in the cryptocurrency world is like a year in the human world.

15. There is no so-called technical analysis in the cryptocurrency world. Short-term fluctuations are unpredictable and cannot be predicted. The only low-risk arbitrage methods are hedging and bit lending; these are the only two proven methods in the cryptocurrency market.

16. The most reliable investment method is value investing, the ideal investment operation is dollar-cost averaging, and the most suitable investment ratio is 5/2/2/1 or 4/3/2/1: 50% (40%) mainstream currencies, 20% (30%) potential currencies, 20% (20%) ICOs, 10% (10%) cash.

17. Do not let investments affect your normal career and related income. Investment is just a potential way to get ahead; no matter how much money you make in the stock market or cryptocurrency market, you must always remember: the ability to make money outside the market is far more important than the ability to make money inside the market.

18. Do not participate in projects you do not understand, do not participate in projects you need to ask others about, and do not participate in projects that cannot be completed alone.

19. Capital determines the lower limit of investment returns, while basic skills determine the upper limit of investment returns. There are many places to learn about blockchain content; free resources can be found on Zhihu, Baidu, and Google searches, and public WeChat accounts are also a good choice. For paid resources, you can buy books (Mastering Bitcoin) strongly recommended, and (Freshman University) also has systematic content. Spending money to buy knowledge is, in my opinion, the only shortcut.

20. The investment amount should not exceed 30% of total assets, and specialized investment funds are preferable. Do not take loans, do not cash out, do not leverage, do not trade futures, do not think about getting rich overnight, and do not play games you cannot afford.

21. If you are still frequently watching the market, fixated on prices, and unable to sleep at night, you are likely not investing but gambling. This is not a good method and will not yield ideal results.

22. The cryptocurrency world may have the most tricks. Before gaining enough experience, do not invest large sums of money. Use money that you can afford to lose to trade cryptocurrencies, so that your mindset won't be unbalanced; strictly follow the plan, use a small amount of non-additional funds to take risks and get harvested, gaining experience in the cryptocurrency tricks is the most cost-effective way to buy experience!

23. The cryptocurrency world does not only allow you to make money by trading coins; there are so many paths to explore, and returns are always proportional to investments. I hope that both you and I can seize this wave of dividends.
