I think to buy the coins at the time of their fall is wrong. I'll wait for when the market stabiliziruemost and prices will go up. It seems to me that to buy coins at the beginning of the uptrend is more profitable. But I am sure that all who buy coins now will make a profit. The amount of profit will be different but this is the interesting market.
I think if you only want to make money with others, you are sure to buy it when it is up, but if you want to take more chances to make more profits, you have to learn to buy on the downside and be the one who took you along with you Instead of waiting to buy back with others when you get back up.
