No matter how high crypto coins go bear market is unavoidable it's just the way the market survives, many people are brainwashed with present market condition that they already forget what bear market is, no amount of money can stop bear market from happening, don't say I don't warn you be prepared.
It's the two way around. Bears and bulls are inevitable. But it should sink in to everyone's mind that when we came from a bull run, the bears are coming next.
In that case, you're preparing yourself from the upcoming possible bear market which is going to devastate a lot of hands and portfolios. It's going to shake the market and will leave those who are tough and has those diamond/strong hands.
That is why we need to sell when there is a bull run and gain profits, so that we can prepare ourselves especially our finances to create a maximum purchase of valuable coins when the market turns bearish. Because its already known to everyone that when a bear season replaces bull season, its hard to earn and make profits but it can be a good start to re invest again and hold them so we can prepare for the next bull season. So its actually a win win scenario after all. No one will lose if you always find the right time to buy and sell.
