when everyone screams Sell, it's a great time to buy. So buy and hold the bitcoins for somelong.
buy bitcoins and put it into coldstorage and stay away from gambling , hyip or any investment , it will be worth for next years
So that will be good. But that is also risky because you can also lose some money if the value will be going down.
It's very simple. You don't lose anything if you don't sell. If you sell in panic, then yes, you'll constantly lose money.
Better yet just hold it as much as possible and dont let your guard down when theres news about the price decrease.
