I think it should be better if OP buys it during in dip of bitcoin so he will get more bitcoin rather than buying right now. When bitcoin is still on its highest peak. After OP bought or invest his money into bitcoin or any other altscoins but i highly do recommend that NEVER invest your full money on altcoins. Some of the altcoins are easily going to dump their coins while leaving those investors unaware about of what happen to their invested items.
