Bitcoin is great! it will be the next digital gold (gold 2.0) a great store of value with only 21M coins.
But when will the revolution reach the medium of exchange sector?
When will a cryptocurrency replace FIAT?
What is needed in order for that to happen? some ppl say LN (lightning network) will help, and that the issue is scalability.
I think it is in the monetary system. people will prefer to HODL the BTC, and use the USD to buy stuff.
What do you think?
