I buy a lot of coins for now, to wait for prices at the end of the year like last year, in hopes of making a big profit
I also do so, it's hard to guess which coins are going to skyrocket so buying a lot of coins is a better and more promising thing than hoping to buy one or two coins.
you don't have to wait for the coin to skyrocket because if you can buy right now, you can sell it when the price increase later. I am sure that this month and the next month, every altcoin will increase higher than now or we can see that the altcoin price can increase before the next month. so if you can choose 1-5 coins right now, you can see each of your coins will give you a good profit.
