I speculate my low-ball offers get filled.... AGAIN.
You seem very sceptical ... are you afraid that XMR could be delisted on POLO as a trading pair?
No I do not think so... And ultimately XMR might be a shiny coin with bright future but I think it takes some time as the big public will pay attention to it.
The possible scenario might be as follows: BTC or ETH will introduce people to crypto. After when people will find the world of crypto they will pick their favorites (for some people it is privacy and then they will choose Darkcoin or Monero, for other people they might want some real world use and they will choose ETH, for some peole they prefer something else and they will choose the crypto that has not been yet introduced to us etc).
I see the future with several parallel cryptos focusing on their own userbase, not necessarily competing against each other but living together (just like now we have in fiat world: Sweden has Kronas, Finland has euros and Russia has Roubles - they are not competing with each other but serving their own userbase).
That being said, the short term we have some chances to go down from here although I also want to hold those btc since btc has brought some nice ROI recently.
I do not see Polo delisting Monero, it still gives more trading volume than most of the coins there, and the criteria for Polo is that they want to make money from fees. As long as it makes at least somewhat sense to keep the trading pair, they will keep it. It is a business that makes money from trading. Obviously they want high trading volumes but it seems it is enough the volume is at least on acceptable levels.
