Yeah that is right, the only difference is that do you have enough money to buy now? And if you buy now, will it give you a good profit after one or a couple of years? We all know that the price today of bitcoin is so expensive and we can't buy one bitcoin easily so the normal strategy here is to wait for a roll back maybe a dump so you can gave a decent amount of bitcoin. The problem now is when to buy since we don't know when will be the price roll back or dumps.
