At its peak, for a short while, XMR withstood over $100,000 worth of daily emission. (23000+ XMR emitted per day * 580+ XBT:USD * .008+ XMR:XBT).
Today's daily emission in USD: ~$8,300
So a bubble in July 2015 could take us to $7+ assuming zero growth of the XMR economy.
How about XMR in 2021? Due to better exchanges, more use, and more visibility, let's assume that XMR can withstand $1,000,000 in daily emission for a short while (as litecoin currently can in 2015 with nearly zero use). With 836 coins emitted per day, that's $1000+ per coin.
I believe $1000 per XMR is not only possible but realistic.
Lets be generous and share our knowledge of Monero with others now while prices are still cheap. I am telling everyone I know about it. They will thank me later if everything goes according to plan
