bitcoin is the first, and it is the one that started everything in crypto, it's the more safe and more developed, i think the other coisn need to prove to be worth more than bicoin not the opposite, there is still a chance to have a better coin in the future, but there are chance to develop bitcoin even more covering the hole and make it the ultimate cryptocurrency, also right now it's a very good safe heaven
I believe it is hard for to see someone that invent a new cryptocurrency that can surpass bitcoin. Besides it high value, bitcoin presented it self as the future of cryptocurrency that's why it attracted so many investers, because it was a sucessful project. Reaching 4000$ worth for a single bitcoin , it still expected to get even higher.
Also, it was litterly a recolution in cryptocurrency world. Bitcoin offered a maximum degree of security and privacy even some banks don't offer. That's why i think it will be so hard, for now at least, on someone to invent another cryptocurrency that can compete with bitcoin
