As starter to something that you still in the process of learning, I see your point and yes, it should not be that much as you can quickly feel fear and when the market fall so hard, that will be the cause of your losing, when fear dominates you will sell your holdings without realizing that the cycle is normal.
Just like how it was being presented, investing will depend with how you guage your knowledge with the market that
you are taken as medium of your investment.
Because experience will teach anyone to make better choices, for beginners it's better to try investing in a slightly smaller amount, so that the learning process doesn't involve too many risks when market conditions fall so hard, this will slightly affect psychology because investing uses Money. Therefore, the investment journey process must pay attention to the level of risk that will be incurred, so that beginners have the right conclusions when they want to do it.
60% might not be too bad for me, as long as beginners hold bitcoin and we all know that bitcoin is a recommendation for long term investment and with bigger profits and not affected by altcoins. the remaining 40% can be used for other investments such as for some of the top altcoins and for Fiat reserves, which is useful when prices start to fall beginners still have reserves to buy back. Buying gradually when you start to understand the investment can also be done, but determine where you will buy it. make sure it's secure.
It's different if beginners understand the concept of investing in bitcoin by taking long-term patterns. But in many cases when market conditions fall and the percentage of 60% bitcoin held by beginners, they will automatically experience panic and will try to cut losses by selling their assets. Therefore I say that knowledge will bring someone to the stage of perfection in thinking and acting on responsibility for the investment he makes.
In general 60% is a large number for beginners when investing in bitcoin, especially when calculated from the total savings they have. In my opinion, adjustments are needed in investing and cannot be forced instantly, because if you want to make the right investment, consideration is needed regarding the benefits that will be obtained and the risks that will be incurred in investing.
