I held some Bitcoin, but didn't bought some when it's at $7,000. I had some though, but I chose to sell it to buy something that I want. Big mistake on my part. I knew BNB coin already back when BSC isn't still released yet so I could've had the opportunity to buy some, but during that time, I'm not interested into exchange coins because of limited knowledge, lack of trust towards exchanges, and I'm focused on other things as well. As for XRP, I also saw it at that price, but didn't bought because... I don't know but what I remember is that this was the time where the project has lots of controversies.

I didn't catch those entry levels, but I don't feel any regret at all. What I always say to myself is that "I don't know that this coin will reach X price." and also "Even Lazlo didn't expect that 10,000 BTC can buy way more than 2 pizzas now." What's good about the crypto market is that, even though you didn't buy at those entry levels or at the lowest price possible, there will always be opportunities that will happen. What we only need is patience to wait for those opportunities to come.
