The right decision certainly hold bitcoin in the long term, even that can be said to be a very long way. We here know that bitcoin has an increasing popularity in the investment things, even more people are now more familiar with Bitcoin. For me personally, I set aside for the long term and some in the short term, I use the short term for if there is a need in my life that cannot be denied.
Short-term trading could give good profit as well, the only requirement is you need to have good capital and you should be consistent in trading, we have the opportunity to make more money here since the market is so volatile, too risky but the reward is very satisfying.
For long-term investment, it's good for retirement, but you should also have a job or business to sustain your needs in order not to touch your long term investment.
