fyi, no currency is 100% safe.
especially not a decentralized currency.
the only way for a crypto to become anywhere near as safe as - say, the US dollar- would be with government insured backing, which is 100% against the entire point of cryptocurrencies....
Besides, even government backed, insured currencies are still susceptible to scams and a ton of other potential security problems.
There is no such thing as perfect security.
