This is the problem people have. They will not not want to buy when the price is low but later want to buy when the price is high. The safest coin to buy right now is bitcoin. If you buy it, it is better not to be checking your wallet balance in dollars. Just leave the coin and be expecting bitcoin to get to $100000. Because the price is falling, some people will panic and sell just like what happened yesterday. Do not do that. Do not sell if you buy even now.
It's actually a problem as much human is concerned we don't try do the right at the right time, any one who fail to buy when coin is low and be target when it's high never calculate well.
Is not all about buying and selling but buying the right one, if you buy shiltcoin that have not value and will drop soon it's if no use even some altcoin that always depreciating .
But any who buy Bitcoin weather high or low will surely have good return but is best buy when low.
