We all saw the Bitcoin going up and down in the past. And this will continue until Bitcoin and other crypto currencies become more and more mainstream or have good use cases. For example, if I have to pay less for products at online merchants thanks to crypto currencies and their fees. Then an additional incentive is offered to use crypto currencies. Or even more extreme, that other people, thanks to crypto currencies, can buy anything at all because they currently do not have a bank account or their local currency is no longer worth anything (like people in Venezuela, for example, who mine to buy food).
