As what i have seen on the coinmarketcap.com for the market price for bitcoin that literally goes down to 6K usd is a good time to start the investment. I am waiting for this moment but still i need more money to invest on it. Well i hope i could get more money the following day so that i could invest in this time where bitcoin market price falls down.
True, the price of 6K USD's already a price which's good to start investing. With a price of 6K USD, I think it's already low enough we all no longer need to expect the price of bitcoin will drop lower again. Hopefully you can get more money so that what you have targeted can be achieved well.
Now the prices went very low in the market and don't overreact if you don't have money for further purchases. Don't borrow the money for investing because suppose if the price won't increase for another year you might be in deep trouble. Invest only if you have spare money left with you.
You're right, preferably we do not complicate ourselves with loan assets, because what we expect it's not necessarily able to go according to whit what we have planned.
I suggest you try to invest into altcoin or token ico who just entered the market, because the token ico when entering the market will fall away from the price of ico and if your good project will soon benefit in a matter of weeks.
