Even though it’s no longer a legal currency in their country, nothing has really changed, they’re still accumulating Bitcoin.
Bitcoin remains legal tender in El Salvador but it is no longer mandatory legal tender, its use is now voluntary. That means businesses can refuse to accept bitcoin payments, and Bitcoin also cannot be used to file taxes or pay public bills.
Honestly, it doesn’t matter much whether you call it legal tender or how you tax it. What really matters is that demand keeps growing. That’s the true sign of success, real adoption. And we don’t need Bitcoin to be a legal currency to achieve that.
Nowadays, whether bitcoin can become a legal currency or not is no longer important because most people only consider bitcoin as an asset/investment and they only use it to make profit. But if we remember the original purpose of satoshi when creating it, bitcoin's failure to become a currency is a failure.
