BTC is a real Bitcoin. It has a developed ecosystem and a lot of supporters. People trust Bitcoin and number of Bitcoin users increase from every day.
90% of BTC Market is SCAM. Non-transparency unregulated platform for fraudsters
BSV is more reliable
Sure, a lot of Bitcoin's trading volume is fake but it doesn't make the cryptocurrency a fraud.
A large amount of gold sold online is fake ar at least impure but it doesn't make gold a fraud.
The person who forked BSV is a proven liar and a scammer.
I wouldn't call BSV legit or regulated because it isn't.
