Yeah I almost think the same as you who make bitcoin as an emergency plan. But if we think back again is very stupid if we sell bitcoin in the stock market is going down drastically especially if you buy 1 bitcoin with a high price you can only get half price from the sales you spend to buy it. It would be better if you save in a bank or piggy bank it will be lighter for you. Can also if you want to try to start investing in altcoin that has the potential for profit.
