NEM is still one of the best systems around and is predicted to recover soon.ICON is in the top 30 cryptocurrencies yet lost much of its value during the past few months.

Though ICON is down right now it is likely to eventually beat its previous all time high.Went to $11 to $3.50, losing 66% of its value. This huge loss is enough to turn many off Ethos. However, it is considered by experts to be the best wallet out there and the most promising one.Compared to other cryptocurrencies, Substratum is the only one that topped over $3 in the market and had one of the most significant losses. Yet it is still a favourite amongst experts due to its revolutionary decentralised system potential.The same story here as with ICON.
