I've been invested in IOTA for almost a year now, and it's basically not moved (aside from the crazy ride that the whole crypto market took). On the upside, it's still (just) above where I bought it, which is more than I can say for plenty of others, so it's got a reasonable level of stability. Problem is with projects like IOTA, they are real (albeit risky) long term investments, and it's not just about sorting out the security issues. Haven't got enough in it to worry too much, but would like to see more tangible developments over the next 6-12 months. Don't want to be treading water for another year.
