Don't actually take out a loan to invest in cryptos. That would be incredibly reckless and irresponsible.
Don't get me wrong, I think Bitcoin,Ripple, ETC, Steem etc. will probably rise. But there is no certainty, so please only invest what you can afford.
I am willing to bet you a million dollars that BTC will rise over $500K USD.
In the next ten years or less, it will rise way above that even.
If not, then I will owe you money.
