Unlike ETH transfers, which require fees, EOS transfers are almost "free". Users only need to mortgage a small portion of their EOS to the system, which allocates resources and then enjoys a "free" transfer service. However, the EIDOS mining project appeared in EOS last month, which strained the CPU resources of the whole network and seriously affected the experience of EOS dapps.
The ETH network is a different economic model. In the ETH development smart contract, the cost depend on how you store data on the blockchain to consume gas. Although there is a cost to pay, but you do not consider the problem of resource explosion.
