Holding $BTC is a must for everyone investing in crypto. In a way you can say it's the "safest" option in the cryptoverse since a lot of people, private funds, banks hold it. It won't go down that easily.
Also note that it's 40% down from its All time high, meaning that there is potential to increase your amount 40%. For example, if you invest 100 you get 140. This will not happen in one day and you need to have patience, though.
If you dream of making 1 or 100 dollars to 100000 or 1000000 with one trade and crypto, i don't want to disappoint you but you will end up with 0. I prefer to be modest with my investments and it $BTC is one way.
