I know, it would be pretty much off-topic and you are one of the worst posters in this forum, the one who is just one block away from insulting the other party. But to make things clear:

It has been said too much but based on a wrong interpretation of what security is! Any PoW cryptocurrency is considered secure unless its implementation is basically flawed. You have low hash rate? you need to wait for more confirmations and you are secure if you do so.

Unlike most authors are used to say, bitcoin has always been secure since July 2009 until  now and its security level has not changed meaningfully. During the last decade price increase has triggered more security requirements and more hash rate at the same time. Security is the equilibrium state between the attacks incentives and their costs.

The beauty of bitcoin and PoW lies in the very basic ideas of bitcoin borrowed from game theory. When attackers get more incentivized to abuse their power (because of price surge) miners are experiencing even more incentives to invest on mining, in long run the security level remains stable, just the same in the big picture. You have always more costs for attacking the system compared to your gains, and it is the same for any state of the network being in its infancy or after decades of growth.
