Hello guys, with the current situations of market can we share some little few tips on how to possibly multiply our bitcoin portfolio without engaging in any ponzi scheme??? 
The only way is with you to buy some bitcoin at this time and wait until the right time to sell bitcoin. You must take momentum when there is a profit margin between the selling and buying price. I suggest to be able to make a decision quickly because if we are late then we could have failed. Believe in yourself and consider bitcoin a long-term investment. Oh yes do not ever be affected with others because it can make a bad panic for the decisions we take.
