BTC should be the number 1 coin to choose for the future investment. If we still have some money, we can choose top altcoins. ETH, ADA, BNB, DOT, XLM, TRX, SOL, MATIC and other top 50 altcoins are recommended to buy. You can exclude stablecoins and meme coins, they are not proper coins for investment. I think we only invest in the coins that have good fundamentals and they have high volatility. Stablecoins and meme coins don't fulfill the criteria.
