It's never too late to enter the trade and one added value when you enter when the altcoin price is fairly low so you won't lose too much money when you study and experience errors.
Our delay in selling can be a good lesson, we can predict prices, we can make more observations to be able to determine the steps we will take, bitcoin and altcoin can we map price movements that might occur, we can see good potential with see price movements that have occurred, so delay does not mean failure, but a fortune is delayed.
There isn`t such thing as late for trading, it`s something that you can do all the time, 24/7. It`s late to be an early adopter, to buy bitcoins for some very cheap price and just hodl, but if you believe in very high price one day than it`s not late even for that, buy now hold for minimum 10 years and you will be an early adopter for many people and you will have great profit from that.
Every day is potentially a good day for trading and making profit, holding on other side is something you do for years, don`t mix those two things.
The thing some of these people complaining about being too late is that they don't take the opportunity when it presents itslef. Like now. If people really are into crypto, then instead of complaining about the hard bear market, look at it from another angle. Here's a good chance to get in at fairly low value so that they won't have any regrets come the time a bull run commences.
