Yes ..... My sons bosses son purchased bot coin many, many years ago - when they were dirt cheap virtually unknown of - the many big customers firm's main client's wages payroll were hacked online, & wanted to pay a ransom in Bitcoin they were cleverly encrypted no way of decoding the payrolls - he foolishly let his Dad use them to pay off the ransoms to this Russian guy ..... He eventually scarpered as the FBI were after him, a multi millionaire now .....
If the bosses' son had held on to them, they would have had a value of millions today .... he's fuming ......his Dads a millionaire too, & would not give a door a bang .......
His son still buys the odd one or two - my son has the odd one or two they are like stocks & shares - they can crash .....
