Bitcoin has been recognised as currency in many countries and as of today its the most liquid & widely accepted crypto currency in the world. However, there is a long list of alternate crypto currencies that are eager to grab market share and challenge Bitcoins dominance. And what about the 21 million Bitcoin limit? Its possible that once that ceiling becomes severely limiting, users will turn to other crypto currencies, effectively increasing the global supply.
Absolutely yes, bitcoin is the most recognized crypto currency in the cyberworld and over 100+ crypto currencies are eager to grab a market share. That 21 million bitcoin is a long long way to run and many years before it will mined all. On my point of view bitcoin is just like a gold, the gold couldn't find it easily a long process to run in order to have a gold thats why its value is so high. Just like bitcoin, the long time will having a bitcoin its value will high which gives us in the future a good profit.
