the market is down now coins are cheap now think it's time to jump in now,can you see that bitcoin will go down even deeper and If you think it will then wait for it.we need to understand how volatile the market is,that it will recover or goes down a little further. If I where in your shoes, I will test and buy bitcoin today and then see what happens, if it goes down, then buy more. If the price suddenly jumps to a level were you can't buy,that's why you will only hear people saying that there's no perfect time to buy bitcoin...
