actually you are not stupid because putting money on lots of altcoin but this is too dangerous, maybe you can have a lot of money if altcoin also pumps in 2020 but if altcoin only has prices like now or more down then you will regret it. if I were you I would still choose bitcoin as the largest portfolio
Actually if a person has no purpose of his money, it's his freedom to take full responsibility of the money he owned. What I analyze with alts investments when bearish market is dominating aggressively, losses is always taking the lead and won't give you such profit compared with bitcoin as an asset.
