I think in some cases it's definetely a good idea to hodl. For example, I bought BNB long time ago. To be honest, I just forgot about having it. Recently, I logged into my acc on the Binance and suddenly saw the current BNB price. So that's the case how you can put some ridiculous money and win later.
This tactic only works if you have correctly identified the coin for the hodl. In most cases, newcomers buy altcoins and hold them, mistakenly believing that they will necessarily increase in price. BNB is a really good coin, especially for those who trade on the Binance exchange.
