This is why hodling too many altcoins is a risk too as you would need to have constant update and price check just to check if your token is still valuable or if the token has already pumped. A good strategy for hodling is having only 5 to 8 altcoins max with the exception of main cryptocurrencies like BTC, ETH or XRP. This is for you to minimize any chance that you can miss an important information about the altcoins that you are hodling.
