My biggest regret when I was watching the ethereum last year on coinmarketcap then I don't even buy it. Now I reliazed the power of holding coins that few years holding can make you rich on cryptocurreny but before buying a coin we should research for it. Now I'm still searching for a coin that has a big potential for a big pump. I'm looking both on initial coin offering and existing potential coins. This is only my experience and opinion regarding this topic.
