Ofcourse if you can make easy money with it, with 'play money', why not. And offcourse people with much money will try it out to... But lending to buy... Omg... no! Just don't do it! I am just hoping that these massive amounts of fiat flowding into the crypto world will go to good projects, that they use the money to prove it can be worth something... But so many coins only have a whitepaper and they are receiving so much funds... It's crazy!
There's lots of margin trading going on, and it has been like that for years. In fact people lend money to buy literally anything fro groceries using a credit card to a house through mortgage. Just don't take a loan that you will not be able to repay. Still, I agree some coins are pumped beyond reason. There is literally no reason for a coin like doge to moon..
