Sitting on XMR is a mistake because there are way too many open vectors in what even the lead developer "smooth" has labeled as alpha software.
Placing large sums of any form of money in alpha software and expecting it to be secure is just plain foolish.
If you do so then ask yourself, am I feeling lucky?.
I agree with you, and I'm not being misquoted here.
But let's be real here, the entire market cap is like 5.5 million USD. That just isn't "large sums of money" when divided among a large number of participants. Its a very low speculative value fairly consistent with the risks involved balanced against what might be significant upside if the risks can be overcome.
Of course what is large to one person is small to another. Certainly no one should invest more than he or she can afford to lose in any speculative investment, and that includes not only any altcoin but any cryptocoin at all, in my view.
Wow, Smooth agrees that keeping any large sum of value is not safe because xmr is alpha. I was holding 540 xmr but will dump it asap. I got to admit I never expected this open admission from the xmr team. In the same post bcx talks about other exploits which again smooth doe not dispute.
