The way I see it is that the best time to purchase a token is when it's quiet, and prices have been depressed for a while. Not just any token though. I look for a large following on telegram, reddit, and other social media platforms. As well as a strong team that is in it for the long haul.
ENG is one of those tokens, and I want to get your thoughts on this project. Is now the right time to invest? Convert my 10 ten alt coins earnings?
I would not advise that you dont convert your 10 alts earning provided you are sure that those alts does not even have a better product, team and community than ENG. I would have even advised that you convert those alts to ETH because there is no way ENG can really stand ETH, when you consider their technology, their product and their community.
ENG is also a good project, but not to stand as replacement or option over Eth. First, you would have even carried a poll out now to see individual opinion of each of the project, you will realize that whatever way you chose to ask the question, ethereum will always supersede in answers.
