Profit takers will be buying again later to get even more cake. Of course, it's possible that they'll never get a chance to buy cheaper (e.g. bitcoin profit takers who sold at $1).
Do not get me wrong, I am doing this also...
I have separate investment portfolio and trading portfolio.
Trading I am doing to get something to do which gives me also a little bit excitement. Investments I hold for long haul and am planning to sell if I need to purchase something bigger assuming the price goes as I wish.
Trading however is the gambling side of me and I am controlling it not to trade too much. If Monero goes viral, there are pretty high chance that at some point it is impossible to get Moneros even sub 100 usd levels and if my trading position is in other currencies, I have lost the opportunity cost of having the appreciating Moneros.
That's reasonable. But think about the current emission. What's $100 x 17,000? $1.7 million dollars. XMR can get to $100 and sit there for a few days. Can it stay there for any significant amount of time with every botnet and internet cafe owner on Earth dumping XMR every day? No.
I'm not sure about this. I would 100% agree if you had suggested a quick move to $5 or $10. But at $100 it is extremely widely reported and a huge popular phenomenon with million and millions of regular people mining it. 200 times the current hash rate is much bigger than botnets and maybe cafes. Many of those regular people are not going to dump small amount of "free" Monero they get from mining, and the excitement of that explosive rally would surely bring in new buyers. It could very well be self sustaining.
