Cryptocurrency is very changeable. Therefore, it can hardly be said that we will never sell some kind of coin or token. While I am very confident in ethereum. This coin should always be in demand, since a very large number of tokens are issued on its platform and ethereum is needed for their movement. However, one cannot be completely sure that this coin will not bypass EOS in the end. Although so far it is not worth fearing, but in the future everything can happen. In cryptocurrency, you should always be ready for new changes.
