The the government of some countries are against the Bitcoin and some are ready to adopt Bitcoin. So what would effect on btc if any government approv the Bitcoin is a legal tender.
Of course, the effect would be drastic, if bitcoin will be worldwidely accepted, the demand would increase, and we will see that the market will reach unimaginable spike on bitcoin price, lucky are those who hodl bitcoin, being it legalized would mean good news for the sellers, i cant imagine how much will the price be.
