Listen against most people in the world or, on this sub reddit, i would recommend investing in a larger cryptocurrency. Although there is so many scam companies using it, and people's lack of understanding in the industry to frame their scam. People need to stop trusting other people's intention towards their money. Crypto is literally completely tangential to this entirely. Crypto is about an individual with the freedom to partake in a trustless, decentralised cryptographic software, and probably the free-est market we have. You dont need a third party, nor did your BF's 'friend.' To be fair its horrible but his gullibility for a quick payday he deserves what happened to him. He's responsible for his money and who he gives access to his pc. Your going to have to find a trustworthy person that can explain to you what you can do. Everything is stored on public ledger you can track every transaction depending on what crypto. Its unlikely your getting your money back because if he bought crypto its in a wallet that dont have keys to. You could call the police but i think its unlikely they'd bother. Your bank is probably your best bet. Good luck with that one but theres noone else to blame. Dont hate him too much he'll earn it back! Also its probably a good idea to sell the tv for BTC.
