Every part of Bitcoin investment has its own risk even when holding, the statement of 'no BTC holding is risky' can only work for investments that join early before ATH price and also well experiences investment.
Nevertheless, we still don't know what will happen to the Bitcoin market in the future cause tomorrow is not promised.
maybe what you say can be very different from what I know, that it is precisely by holding bitcoin for long-term investment that is for every 4 years (halving) it is certain that there is nothing that makes the risk will occur, but it will always be advantageous because it would there is an increase. but if you do for day trading, you can be sure that risk can occur because prices are always changing quickly if you don't analyze them properly.
If you don't have much experience, you should invest in bitcoin or trade carefully. A conservative and cautious approach involves moving averages and slowly either selling or buying. If you do this, you limit a lot of harm from what could go wrong in the long run.
if it is to be used as a trade, it is clear that the risk that occurs will be very large if we are not smart to analyze the movement of bitcoin when it goes up or down, because the movement of bitcoin is very fast and can go up and down very quickly. it's different if you buy now and will use it as an investment by holding in the long term, which is known as the halving period. then it is certain that bitcoin will increase and reach renewable ATH.
