Do you think that there's a possibility in which tokens could replace traditional cryptocurrencies or altcoins we know and love today? My guess is that they could in the future because it's much easier to develop a token on an existent blockchain than starting a new cryptocurrency from scratch with its own independent blockchain.
Given how popular tokens have been lately (especially on the ETH blockchain), they could be the future of cryptocurrency as we know it. I've seen many ERC-20 tokens on ETH with PoS capabilities (such as Accelerator Network, and PoSToken) and PoW capabilities (such as 0xBitcoin). Their usages and purposes are the same as an ordinary cryptocurrency.
Nonetheless, what are your thoughts about this? Do you think tokens will eliminate the need to create an altcoin from scratch altogether? Will they replace traditional cryptocurrencies? Or will they co-exist?

The only one thing what is better when you use ERC-20 tokens is that it is really easy to use it, you dont need to have hundreds of diffrent wallets.
