For those who enjoy baiting phone scammers (I certainly do!), there is a chap on YouTube who takes it to another level. He gives them access to a 'virtual machine' (basically an entire separate computer system running within his computer system), and then gains access to their computer, deleting whatever he wants - the ensuing anguish is very cathartic!
Anyway, bottom line for investing, crypto or traditional- use established, reputable platforms or brokers, not some random guy that contacts you and promises you rapid, ridiculous returns, realise that your capital is potentially at risk and for god's sake don't invest in meme stocks like GameStop when they're at their peak after they've been artificially pumped stratosphericly higher than the company is worth!
Oh, and just a word of warning after a few recent experiences - if anyone ever rings you and asks you to confirm personal details like DOB, account password etc, before you can continue, remind them that they rang you and could be f*cking anyone, and put the phone down. Nothing is ever that urgent.
