Talking about the risk involved investments, it is not a new new thing because life is full of risk it self, so as a good investors one should always have it in the back of his mind that there are two things that is common which is losing and profit, which i see that, the losing aspect of Bitcoin is very rare once you make use of buying the dip and hold in a longer term investment, so we should risk to win because it is only those investors that is not afraid of the risk involved in Bitcoin that is making it bigger, so is good to risk to win.
I observed that forum mate like you POPOLUV, has refused to reframe or adjust emphasising buying the dip as the most suitable, best and safest strategy whereas it is not, I have seen other users correcting you with such expression even in other threads, for more clarity while buying the dip helps in buying more Bitcoin in lesser amount it does not make it the best, you can buy the dip and it dip further or you can be waiting for a desired dip and it never comes making you to miss buying opportunities, there is no much associating with Bitcoin investment if our investment money is coming from our discretionary income because you are doing it without struggling to take care of your basic needs and responsibilities, for Bitcoin volatility the DCA is effective over a long term investment though every other strategies have their own distinctive functions.
Also, they seem to also relate Bitcoin investment to gambling, saying thinks like risking to win, and it's wrong, people need to stop treating bitcoin investment like a gamble and only waiting for a dip to buy which is also wrong, waiting for the price to go low before buying everytime you want to buy also marks you out as a trader not even an investor, and most trader are just gamblers masquerading as investors.
