I would love to see Ethereum will recover fast from their congestion because this is one of the main part of Cryptocurrency that people will consider the invest. Being the top Altcoin isn't easy that's why some ICOs and Altcoins are falling apart due to lack of developers and and staff that could carry out all the issues concerning major problems and Ethereum has the best group of developers and community for carrying out all the issues.
Although recently people experienced a bit slow with their transactions but there are still huge numbers of investors and supporters.
