The more XEL I have, the more I'll be able to obtain computing power to mining? Then, the demand for this currency will be insane! Or not? Is it true that Elastic has not yet released because there are tests proving the total security of the network? Could one list for me what arbitrary activities besides mining could be carried out? Sorry, I'm a beginner!

XEL is needed to create a working job for the network. The XEL will be distributed to the network (nodes, supernodes etc)
