My biggest fear at the moment is if quantum computing becomes mainstream and hacking the network becomes ordinary.
Am sure then, bitcoin can become worthless as investors shall fear bitcoin.
Yeah this is the most people's problem who using bitcoins because we have that fear of our bitcoin will be hacked.Bitcoins have no customer service which is need to be done by the bitcoin team soon.Bitcoin offers no such protection: transactions are irreversible, so the buyer must trust the seller to deliver. Many Bitcoin users say that this is a feature, not a weakness, and simply requires the buyer to do their due diligence before sending a seller their money. Plus, irreversible transactions protect sellers from fraudulent chargebacks.
