Tradings are one of the biggest mistakes you can make because we all know what will happen to the bitcoin when we are not trading and that is cause lots of people quit
tradings because it is to hard to do.
Basically, when there are people buy on certain bitcoin price and majority of them just hold bitcoins, the price will stay on that price they bought it unless there will be other investors or ordinary people that will gonna buy bitcoins and actively trade them to either dollar or other altcoins - then the price of bitcoins will regularly goes up or down.
