Investing in Crypto is good and profit oriented.. There are alot of benefits associated with investing on Crypto assets ranging from Profit making, decentralized feature, accessibility etc especially an asset like BTC which is very popular in the crypto world.
It is clear that the aim of investing for some petty investors is to generate profit either on a long or short term duration.
With the trend of the market over the years though not for all assets but looking at that of BTC, it is keen that as time goes by, it's price appreciates. Proving it's strength of volatility and it's worth of investment.
As for other ALTS, it is good an investor makes a wide research about the token and it's price history before placing an investment. But the likes of top ALTS like ETH, BNB, SOL etc are worth investing too.
