I am used to investing in something that I use on my own, for example, I use Tron chain, so I invest in TRX or I use Binance Smart chain that is why I hold BNB. When I look for a new token to invest in the long-term I use coinmarketcap that is the best place to look for safe investments. There is a table top-100 with the most popular tokens. I choose one that is on lows or at least not on highs and investigate details about it.
