How can someone know the perfect time to pick such a desperate gamble? We win or lose in trading or holding bitcoin but, I presume with the help of experts in this forum who have gone through thick and thins in this market, good guides or rules can be shared for users and newbies in the forum to have a grip on the market and know if borrowing is appropriate. It does sound thoughtless but, borrowing is part of the business. And we must prepare for the best as well.
There isn’t perfect time for you do that, you’re always going to be taking a risk. The question is if you happen to lose the money in the market, would it be something you’d be able to deal with? If it’s something that you wouldn’t afford to deal with if in a case where there is a loss, then you will have to be very careful steer away from it. Sure there are people who have done and it worked, but it’s very rare for you to see such thing. So, it is just up to you and what decision you want to makes and making sure that you’re hundred percent aware that you’re taking a risk in market.
