All this market going down is caused by people who think they are smart they think they will sell now and buy low later , then the price will go up rapidely they will fomo into it rinse and repeat until they will loose all thier crypto, best strategy is to hodl .
two things. altcoins are going down because they need to go down as the dumps are coming after all these months of pumping them. investors are exiting!
also there is nothing wrong with selling. in fact in most cases, even for bitcoin, you need to sell your coins when you see the drop starting. the problem is timing. newbies sell when it is already too late, experienced investors sell when the drop is just starting and has not yet reached bottom.
like warren buffet said: "if you are not welling to hold a share for 10 years don't plan to hold it for 10 minutes."
Warren Buffer does not understand the cryptocurrency market and is probably not even familiar with how the pump and dumps work. I personally have made a lot of profit by only holding a coin for a short time. not exactly 10 minutes but mostly less than an hour. in fact the bulk of my profit is like this from the altcoins' pumps.
But most of the people that are in market now are kids they think they will make a quick buck in crypto ,they end up loosing everything.
you end up losing only if you hold altcoins in my opinion. but anything else that you hold: bitcoin, gold, stocks of a good company that is expanding,... you will make a lot of money.
