Any service from third-parties.
It's always have possibility to become a scam, do you know some legit service that turns on to be scammed? We already see that. So, IMO people should be aware of the risks and use the money they can afford to lose.
IMO, more than 50$ with type crypto like (BTC) better to withdraw and swap them on exchange. These kind of service are just suitable for low amount. Who know, in the future (Stake) add exchange service 3-5% fee ~XD just like other exchange, so they can drain out more money from user ~XD.
I think Eddie already stated that they are not going to create an exchange service, because of all the regulatory requirements and "red tape" that needs to be done to operate that. I think it is just too many hassles to get it off the ground and then to operate it, within the regulatory requirements of the different countries.
They are comfortable with a third party like Dinabot, offering those kinds of services. It would have been nice to have a in-house service, because Dinabot can be a bit tricky and it is expensive.
