Hmmm, I am not sure about the bitcoin opportunity for the future. Seeing the fluctuating condition of bitcoin this year makes me not believe in long-term bitcoin investment. If only for short-term investments, it might still be potential, but for long-term investments, Ii is very risky. I prefer to save money for my children in sectors other than crypto currencies. I prefer to save money for my children in gold. Gold prices will get better because I have never seen the price of gold drop dramatically. Gold prices tend to be stable and grow more and more with time.
