Of course now my portfolio value is down at least 95% or so because small cap coins always lose way harder during a bear market then the big ones.
If you are willing to take the risk then you are free to do so although in the end you should realize that the big profits you get from altcoin are down to luck. I mean every altcoin you own has no real use case, you just hope for volatility, and if you make a profit sell it and convert it immediately to bitcoin.
This needs proper DYOR if you want to pick a new project on your own, it's a high risk that could anytime you will lose. I sometimes do this and follow the trend and the hype is over and your profit was there, there's no need to become greedy and wait for more profit to come, divert it into a new one that has a trend. It's very risky but if you're lucky enough it's profitable.
That's why if you want in a safe position in investing crypto, just give a large allocation in investing Bitcoin in your portfolio because every coin will follow the Bitcoin trend, if there's a bull market, every coin will follow.
