Holding can be the better option at present and if you have captial with you then you should buy more bitcoins as this is the right time to invest in bitcoin as the prices are lower at present and hold if for 10 years or so anc then you can earn a huge amount of profit.
Holding is the best option, but you should know how to store them safely. Wallet hacks and robberies are quite common with Bitcoin, and I don't want some lowlife scum to steal all of your hard earned coins. And holding them for 3-4 years might be enough. By that time, either Bitcoin will be replaced by some other form of currency, or it will be widely adapted and accepted worldwide.
Exactly. Holding sounds great. Atleast bitcoins that we hold are safe rather then going for gambling and loose the bitcoins. And ofcourse need to beware of scammers who are keeping watch on our hard earned coins so need to take care of it. And yes it is the future so it is better to hold them for a while.
