I buy bitcoins when the price is pretty high and when the future is also pretty attractable, right now as a example I would not buy it because of te fact that the bitcoin is too high for me to invest again in it..
Lol you say that you want to buy bitcoin when preety high price? bitcoin prices pretty high now? why do not you buy it. I think it is quite risky to buy when the price is high bitcoin because it may be some time later the price will decline. be careful with it
