Trading is a risk. It's always stated only risk what you can afford to lose

else you could put money in mutual funds. But even mutual funds are risky. So why not take some more risk and earn more profits which in trading could be earned if good techniques are used.
Correct, trading is just like gambling. It is very risky but if you know how to manage your risk it is also profitable tough.
For now, while the crypto market suffers the sudden dump, I much prefer to HODL my bitcoin for the long term investment. It is the best time to invest and accumulate more than you can afford. Because you can't earn investing in Bitcoin in a short period of time. It needs to have patiently wait.
I agree. You could hold some and may be invest some into algo trading
