Thank you very much. I wrote this post because we have to be aware of what we should do in this business slump. In Japan, we will have to pay 10% consumption tax since October next year 2019. Extra business slump will be waiting for Japanese people. when I think what I should do to help myself and my family anyway, I think cryptocurrency or stock might be good. The idea of working for a big company is the best is a wrong idea now. Heaven helps those who help themselves. we individuals must do something to help ourselves.
