I regret when I ignore stellar during its distribution phase. I thought it is just another shitcoin but I was proven wrong. I also agree that stellar is a good hold. Though thei=https://blockonomi.com/ibm-partnership-stellar-xlm-in-jeopardy/ partnership with IBM seems in jeopardy, but the XLM creator denied the rumor.
This one is good for trading and not for long term holding unless TRX change the way they do their marketing and focus more on development of the project. More work less shilling.
I agree, they have proven their worth but I do not think this coins will go mainstream because of its anonymity feature.
