All traders, including seasoned pros, make these errors, for which they ultimately pay a price. The primary prototype that a trader should control is greed. Beginners and traders succumb to greed and overtrade, which leads to blunders. I am aware that keeping is occasionally preferable, which is why they always recommend trading within your means. If you go over budget and trade with your savings, you may be obliged to sell the coins at key moments when keeping them could have been a better choice. Act and make investments as such.
This mostly applied to investing, a trader isn't supposed to hodl unless you're trading for a very long time. Trading naturally should do with you taking advantage of the price difference in the market and that means you can buy and sell your coins as many times as possible even with in the interval of a day. As a trader your major concern should be how you can profit from the market now and not in the future.
Future thinking are for holders and they shouldn't care about the current movement of the market as their strategy should always involved holding for the future. You can be both a trader and an investors as both are profitable when you understand what you're doing and doing it right.
