Scalling problem? Solved!
Thats why I love ETH dev team. They really working hard on any issue. And solution come really quick.
https://github.com/ethereum/EIPs/issues/648#issuecomment-310634423Some short quotes from explanation:
Transactions going to an ICO can happen in parallel to almost everything else, so the ICO would not interfere with normal traffic the same way. In fact, Status-style network congestion would not be possible unless there were 8 ICOs happening at the same time.
ERC20 tokens can be parallelized (ie. transactions sending MKR and transactions sending REP can be totally separated)
Thank you Team!
