Stop thinking that, you're not an investor if you have never experienced selling at the wrong time or not holding a coin that turns to 100x profit we all have a share of that experience, there are no investors who made a profit from all the coins he invested, even the best investors who have good average in analyzing have fallen to what you've gone through.
We are going in a circle price drops to recover again, you're lucky if you have funds to allocate at the time that the market is in a huge drop, besides selling coins at the wrong time, not having funds to allocate when the right time to buy and opportunity is there is another regret of investors.
