I disagree with you when you said there is no best option when it comes to bitcoin investment, if a newbie goes into Bitcoin trading it won't be the best for him at that moment the best for him at that stage of his Bitcoin career is long term investment just buying and hodling, there are best options for Bitcoin investment if you choose the wrong part it may delay your accumulation journey for example waiting for dip.
A Bitcoin investor should not treat holding and trading as the same thing. Trading is generally risky especially since Bitcoin is the most volatile currency an investor can lose his money in a very short period of time. But if he accumulates his bitcoins long term, he can protect his wealth from volatility. At the same time he will be able to hold bitcoin uninterruptedly. A trader may gain small amount of in short term by trading bitcoins but if he holds then he will be able to grow his bitcoin portfolio in long term. If a trader tries to hold bitcoins regularly according to his ability, he can definitely be profitable in the long run, avoiding the tendency to make a profit. If MicroStrategy was trading Bitcoin they could be profitable, it would increase its profits in the short term, but despite that possibility, the company is focusing on bitcoin holdings. In the long run a trader may be worse off but a bitcoin holder's wealth will continue to grow.
