Do you think Eos will surpass Ethereum in 2020?
I believe it can be!
it's quite hard to tell in 2020. eos beats Ethereum when speed and capacity is concerned. but Ethereum leads eos because majority of tokens are based on eth. if eth doesn't improve and network congestion will be a frequent happening, then new projects may opt to use eos as their token blockchain.
one intriguing part on eos is the dpos where the blockchain is maintained by few chosen servers. some people like it, but some don't.
