hello sir.. good day.. it make sense when you buy bitcoin.. now that the price is still on the sailing i mean not just too high or too low.. but its even better to think that we buy a lot on the past few months.. and seeing that it goes up around 19,000usd compare to the price right now.. it can still offer in return.. but when you say 30,000% it doubt it.. this year maybe its impossible.. maybe in the near future if your going to invest your money in a long term basis.. hopefully i help you to answer your question mate.. God bless and thank you so much..
