all new coins now are nothing but copy scam coins.
because there are no good coins created since long time, most users are making copy paste coins for quick profit
Because there is no need for the xxxth shitty Bitcoin clonecoin with feature xxx.
Because the 99,9% of new alt coins are:
- copy/paste of other coins
Copy-paste coins certainly aren't a new development though. The animal coin and country coin crazes of 2014 saw Litecoin-derived scrypt clones reach enormous market caps just because their devs slapped on a new name and logo to their coin.
I would look for altcoins that have the best combination of all those things and invest in that, I think you see the same projects in the top spots for two reasons. You have a first generation of altcoins like LTC and Doge that had the best possible timing with no added value. And then you have a second generation of altcoins like NXT and Dash that actually bring value and innovation.
I would say that when Litecoin was launched, it did bring added value. However, it was also launched a very long time ago when the altcoin scene looked very different compared to today. Litecoin was able to merge the technical innovation of Tenebrix's scrypt algorithm with the fairness of Fairbrix's distribution while avoiding the latter's inherent bugginess by having the code based directly on Bitcoin. Litecoin allowed CPU miners to mine when Bitcoin mining was dominated by GPUs and then the same for GPU miners when Bitcoin mining shifted to ASICs.
Dogecoin's contribution to the crypto community was probably its innovative marketing rather than any sort of technical innovation.
