I am always amaze every time I imagine how much power does Ethereum blockchain has when processing transaction for every tokens it supported. There are millions of transactions are being process every single day. Just do the math. Decentralized exchanges using ETH blockchain plus online wallets like MEW, Jaxx, coinomi, Eidoo, etc. I always have this feeling that ETH will become number 1 someday. Who is better for you? ETH or BTC?
In actual bitcoin is more faster then etherium , but surely in the present time if you will make transfer with the bitcoin and etherium at the same time , then you will found etherium is more faster then bitcoin , here the main reason is that bitcoin have bulk amount of users who are making transactions per second, but here etherium have less amount of users ( in comparison of the bitcoin ) that why etherium Blockchain is not facing any type of the traffic for the transaction and giving better speed of confirmation even at low transaction fee .
And decor factor of the token transaction is that , token system are only read and write data only system , that means , data will be change at one place and add at another beneficiary user's adress , so there is not traffic due to token transfer .
But don't think that even with this fastness etherium will go to number one , it will not happen in the future because the main reason is that team of bitcoin is not at paused conditions , they are doing work to make bitcoin more and more better with new new Implementation of the techniques .
