We have other investment that we can make money with, importation and exportation and also real estate management and also gas plant business that will be given weekly and monthly income depends how broad is the business and management, sometimes people do teach their children bitcoin and its not bad but let us teach our children other investment that can profit them as we think that bitcoin will profit then in future.
I agree with the OP on this point.
Many say here that Bitcoin is the best investment and blah blah praise Bitcoin, it's a little boring. But regardless of how you use Bitcoin, you still need money or fiat to buy it. Where will the money come from? work. Never risk all of your fiat savings, especially if you decide to trade Bitcoin.
