the ethereum price in the future can reach the price of $ 5,000?
If you have strong believe before end of current year it could reach to this level than you can't afford to miss this golden opportunity to become next millionaire. Take loan and put all in into Ethereum it has potential to explode soon.
Please, never advise someone to take out a loan to invest with. Worst advice ever, even if the investment is crypto/eth.
I took 2015 a loan of 50.000USD to buy ETH. It was my best decision in life.
