I totally agree bitcoin/crypto changed my life forever. Just to share my story because of this I was able build my own house. I am not doing this as my full time job but before I planned to do it however when I saw the volatility I changed my mind. Not only financially because of this industry I learned a lot about economics and business related subjects and as I move forward I will not stop. 
what is certain is that bitcoin can save businesses between countries, because inflation in our country's currency always happens every year, so with the alternative currency, bitcoin, we can use it to make payments between countries, because the value of bitcoin in all countries is relatively the same, so trading with bitcoin will be free from the threat of inflation that always comes every year.
