I will still remain with bitcoin I will not cut from bitcoin because bitcoin did a lot for me when there was a tough time for me and I can forget the way bitcoin help me and the fact is thats its price can also go down some time because its a very good currency and it want to be on the top of all currencies because its mission is to end the world poverty and for that bitcoin need to be more popular and strong so bitcoin price will be always high.
