It is true to buy bitcoin bitcoin at this time the price is high, but to buy it according to me there is no word of delay, but if you hesitate to buy it wait until bitcoin the price down, but of course to predict it down what rise not easy, it is now bitcoin price rise , but it could be up again, and could instead go down, but if suppose we've bought it even the price drops yes we just wait bitcoin up again, or can be bought altcoin we can make treding.
