From the time the op made this post until now, if he had held his profit and holdings the should be glad he didn't sell then because the price of Bitcoin has increased to more than 2x since he made this post. This is a strong evidence that holding for long is the best strategy toward making good profit from Bitcoin with limited amount of risk compared to trading your coins which could lead to loss and if not careful you can make the mistake of sending to the wrong address. Holding is much more relaxing as long as you use DCA and put in small fractions from your earning.
That's true , when it comes to investing in Bitcoin long-term holding is just the best . Most always in a haste or should I say most people just want to make it quick , and deep they know that things don't work that way that's why most of time endup losing their money in trading due to trading with half-size knowledge, and also investing in Ponzi scheme, because they want to get rich quick .
While they can just buy some nice quantities of bitcoin, either by lump-summing or DCAing. I know is not an easy task but with nice principles and discipline one will be able to pull it off. Inorder to secure a smooth bitcoin investment (holding) for themselves.
