As I wrote already on another forum.
If we take into account the latest developments, I could all recommend SCS (Speedcash). Why? Yes, because, the technology is already working:
1)Scash BURST (Blockchain Usage Regulated & Sustainable Tweaking) which makes it possible to temporary accelerate network 10x more from wallet.
2)Scash Vault: ability to store and validate.

Plus, soon there will be a web wallet.
