For how long can I hold edgeless tokens at myetherwallet? EDG Wallet available?
You already have the wallet in your MEW account and you are free to transfer that in exchange sites if you want to sell it.
With your questions about holding, make at least 1 year, the price will be at least $1 as predicted.
