I got your point, bitcoin is invented to be used as an efficient payment system but due to the high volatility of the bitcoin price and the huge growth of the price over the years, it becomes more attractive and profitable investment.
actual bitcoin investment if used is very easy but this lack of development in technology today is not easy
Investing in btc as of this time is not that realistic but I do believe this will not last longer. I am very confident that everything will be better in perfect time. I keep my faith for the new btc come back.
