BTC is unique because it makes it easy for new wave of currency exchange, it blockchain has a unique wallet address, is not easily comprises to hackers or scammers, it benches on volume of communities members, it's God fatherism to other altcoins. Is transaction made easy and key or password individuals oriented. Bitcoin trades in a every sphere of market.
You left all the main points which make BTC unique from (you did not mentioned what but i assume you are talking about) Alts. For example:
- BTC is mostly decentralized and Alts are mostly Centralized
- BTC is based on POW while all other alts are based on POS
- BTC is most adopted and has the most volume in trading in market.
- BTC is hack and fail proof unless a owner of BTC make some mistake or fall prey to any offer which results in losing all of his BTC.
- BTC does not trade in all sphere of market only in those countries who allows it. But to some extent you are right.
I did not agree with your this point
it blockchain has a unique wallet address, is not easily comprises to hackers or scammers,
because, every other alts coin or alt blockchain will generate you random address plus BTC did not generate you address the wallet you are using will generate address for you on what basis that i never tried to find out but point is, hackers and scammers always find a way to infiltrate user's computer/device to get unauthorized access to BTC wallets.
