For a 5–6 year investment horizon, I would generally consider BNB a stronger long-term investment than Dogecoin.
Reasons:
BNB has real utility on the BNB Chain ecosystem.
Trading fee discounts and other uses create demand.
BNB has periodic token burns that reduce supply over time.
It tends to be less dependent on social media hype than DOGE.
However, DOGE can sometimes produce larger gains during speculative bull runs because of its meme-coin popularity.
A balanced approach could be:
50% BNB
30% DOGE
20% Terra Luna Classic (if you want higher-risk, higher-upside exposure)
This gives you a mix of:
Stability and utility (BNB)
Large-community meme exposure (DOGE)
Speculative upside (LUNC)
If your goal is turning a modest weekly investment into the highest possible value by the next major bull market, BNB is the safer foundation, while DOGE and LUNC add more upside potential but also more risk.
