My advice would be to buy now only the coins that haven't increased by 300% in the past 1-2 weeks. You must wait for those coins to be red again. I think its a bad time to buy now, as the prices will have to stabilize, that means there will be a dip.
I think now the market is just right, no need to wait a dozen days. Because some altcoin, like bitcoin, do not go down at all. I do not want to go back to regret it.
