This is the problem so 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 use checking your wallet balance in dollars. Just leave the coin and be expecting bitcoin to get to $100000. Becuase 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.
