I agree with you sir, all your strategy you've stated here is definitely correct but because of the price decreased your investment is affected for almost 1 year start from December 22, 2017 until now. So we don't expect the big profit this all year round maybe next year we hope so.
Yeah... I get that you are concern about the prices but when you trade Bitcoin with a more stable coin like USDT, this will help solve the problem with the change in the market price of Bitcoin. The best thing to know and understand about crypto trading is knowing the past and current trends.
