What coin do you want to buy? Just look at the graph of its price move, just buy when it is in correction. Don't force yourself to buy when it is still at a top price, it must drop again. I guess we are still at the beginning of the next bullish, so be patient to buy at the right time. Crypto prices won't increase suddenly, correction and dump must follow it. I am also planning to buy more coins, but waiting for the right time to buy again. Some coins that I am targetting are still increasing, I wait for them to decrease.
