It looks like this is quite promising when we save a bitcoin for long periods of time, a year ago the price is only around $300 and has now reached $1200, if we buy and sell a year then the price will menapai $2500 or more.
This is how bitcoin really good for saving in long term or run, many people experienced that, because they bought coins in early time and hold it for long and now they are gaining profits, maybe its risky because there were time of coin value crashed down yet they continue on believing that it will rises up again so they got what they really want a big profit.
The key in trading like most things in life is timing those that have been able to get out of bitcoin and then back in at favorable prices have probably made a small fortune by simply waiting for bubbles to burst and if they shorted bitcoin as well then they earned in the way down too.
Nothing more safer than that. Just waiting and taking that opportunity when it gets so high that you cant believe it anymore.
That is just the time I sell when the price is impossible to think that it would happen.
Well, a little profit could also do make it but you will also have to think the time when you again.
Remember always that the buy rate is way too higher than the selling price. So you will need to consider that.
