I don't think we can rely on bitcoins or a particular cryptocurrency and invest in it for our child's future.Its too risky, cryptocurrencies are volatile and hold the risk of crashing for many reasons and some countries are even planning to ban bitcoins.So we can't entrust our child's future on bitcoins.I agree that Bitcoin is the first of its kind and has made many people millionaires and even billionaires but we can't predict the future anything can happen.There's a possibility that many new cryptocurrencies with better technology is created,infact there are already a few cryptocurrencies which have better technology.So let's not rely fully on cryptocurrencies and let's find some safe and sound methods to brighten our children's future.
