The ease in which I was able create my own crypto currency wallet by myself without any help from anyone else or software programs - just one click! Creating multiple accounts at different exchanges so as not get charged with double trading fees (or more).
It does feel like it would be easier if they had some sort manual process you could go thru instead having people behind those computers do everything manually but thats how its supposed too work right? Anyways this service has been very helpful when tryingto trade alt coins since there arent many platforms where your actually allowed access all these wallets directly yourself rather than paying someone hundreds per month/year who can make trades easily etc..
