This is PoW. That's the technology Satoshi invented, and that's the most used one. Beside giving your altcoin a true value unlike the valueless PoS coins, this is the strongest way of securing a coin if you have a good decentralisation of the miners, and enough miners, of course !
I see that POW is still better mining method but how well we can choose the mining method.
POW and SHA Algo will is the best one at the present.
Thanks for sharing for your opinions. While Proof of Work may be energy intensive, it does better in securing the network than Proof of Stake by making it a truly decentralized way of minting new coins. I've never found PoS a great way to secure a cryptocurrency, as those who prove to have the biggest stakes on the network might gain control of the cryptocurrency. While there are many PoS coins out there with good devs, most of them are very inexpensive when compared to PoW coins.
In the end, I think that I might choose dPoW for my new altcoin since it aims to secure the cryptocurrency using Bitcoin's hashrate. I've found this the most innovative development among most altcoins, in which I think that it will be applied on other altcoins when Komodo launches. Just sharing my thoughts.

How does that dPoW works ? Are people actually mining it or is it just automatically computed by Bitcoin's network ? You're right about the PoS coins, because they tend to have a minimal value compared to the PoW giants. By the way do you see a PoS giant ? No. The market has elected the winners.
