Being wealthy after only one night for a trader is not a simple thing. To be successful, they have to lose money many times, even to borrow to get money to continue investing. So nothing succeeds without experiencing difficulties. Patience is a must when investing in cryptocurrency.
I don't think borrowing money is necessary for investing. Also, there had been cases where trader became successful only after one trade.
Look at the example of people who bought bitcoin in 2009 and 2010 and are still banging it.
