Why is he pressuring me to add more funds? Wouldn't a professional crypto trader be trading on a more popular site, such as Coinbase?
Am I being paranoid thinking that he created webulltradingbot.com and is now a rogue YouTuber trying to scam people out of their money?
This is almost 100% SCAM; such posts have been going into circulation for a long time, and many bitcoin experts have warned about this particular site because many people were scammed in the same way you claimed to have been scammed.
Following influencers blindly without having your personal knowledge can lead you to financial breakdown; always learn before you invest in any platform or website.
The first mistake you made was sending the money in the platform because you will hardly have access to withdraw your funds; they will ask you to put more money in to be able to withdraw your money.
The lesson you have learned from this is that we should do research before investing.
