My understanding of the blockchain and bitcoin is not very clear, but I see from some articles. Before bitcoin broke out, many people lost their bitcoin because they lost their private key or made the wrong address. And the number of lost bitcoin should be a staggering figure, then these bitcoin really can not find it back?
Or will there be other ways to make up for this regret?
Dissappear, maybe the words that are suitable for that. The only way to access those address is private key (except for exchanges address), If it's lost or suddenly deleted. You can said good bye to your asset. Impossible to recover it back,
