Well, I really think you missed my point mate, was pointing at a beginner who's mind is made up on trading, so to make sure he does the right thing first by accumulating Bitcoin first until his target is met before thinking of trading, I would introduce a mindset of accumulation as primary and trading as secondary. Just a calculated plan to get such a person to have his investment in Bitcoin first in order to secure his future. Most times while investing in Bitcoin consistently such person loses interest in trading and remain focused on his investment. This is just a mental hack to direct a new investor who previously had intention of trading that there's a better future in investment and it should be considered a priority.
If you deal with people so much, you'll know that a direct refusal sometimes triggers resistance in them, so identifying with their intentions to a limited extent makes them more comfortable and most times at the long run, they get comfortable with your Idea and forgo the wrong motive they had earlier.
Yes, I agreed with you that every beginner should try and start by accumulating Bitcoin first before rushing into trading. Whether the beginner has a mindset of trading at an early stage, it would be a very good idea to start with Bitcoin investment first. By doing this, I believe even if they later start trading, they will understand the difference between investing in Bitcoin and trading Bitcoin.
Some newbies who want to start with trading at their first stage in the cryptocurrency industry don't even know the advantages of investing over trading; all they know is that they want to make money in bitcoin but later after starting trading they lose everything money they have. Some newbies who have lost money in trading might have avoided these losses if they had received good advice to start with Bitcoin investment first. Many of them by now wouldn't be calling Bitcoin a scam because it may be possible that they will still have backup of Bitcoin they accumulated at their first place.
