I guess it is not a good idea to compare Japan's stock with bitcoin because one simple different is bitcoin is having adopters from all over the world and I am not seeing anyone from my country not investing with Japan's stocks. I remember there were lots of topics by 2015 which talked about what if bitcoin would not be moving forward.
Like anyone, for me too the future of bitcoin is a mystery, everyone is unsure as to whether there is going to be another all time high price and Bitcoin beating the last all time high price. But if Bitcoin doesn’t beat it’s last all time high price, I wouldn’t be much worried about that, it doesn’t mean that you wouldn’t be able to make any profit, there will still be some fluctuations and you will make profit just like we are seeing it now. I’m very okay with the price and most times the price is nothing that I worry about because I know that things will always get better.
