What is max price you guys think it could hit?
1000s, but most coins have a max of trillions of marketcap based on the market they are attempting to corner. What I try to figure out is the potential market (digital cash, M2M, File Storage, ETC), who are the competitors, what percentage of the market will the coin likely capture and what are the chances of gaining that market. Once you establish those, you can monitor the coin and look for any competition that may arise or a new achievement that may better the chances of a competitor (though you can hedge to mitigate risk).
So as an example:
Monero:
Potential market: digital cash, black markets, tax evasion, secure business and military spending--these are growing digital sectors that have real world use in the trillions. Assuming they continue to turn digital and Monero can grab a healthy percentage of that growth, Monero's ceiling is in the trillions.
Competitors: Bitcoin, Zcash, etc.*
% of market: based on the need of consumers to have max privacy and the absence of major competitor, this likely is >80% once Bitcoin's privacy failures are acknowledged by the public and consumers move to more robust solutions.
Chances: coinflip, based on new solutions such as zstarks, mimble wimble, SPECTRE (not spectrecoin) Monero has to continually maintain its status as best-in-class privacy--this includes researching solutions that may create better privacy and more efficiency. While the lead Bitcoin has had in this market has dwindled and Monero looks like the succesor, there are more robust privacy solutions that could overtake Monero if they do not upgrade to match the competition(though all indications seem, research, planned forks, ect, seem to indicate that upgrades will be a permanent part of Monero's future). The Black Swan is Bitcoin in this competition as it could refocus on fungibility and use network effects to retake its position.
*There are many coins that have claimed to better than, or equal to, Monero as far as privacy is concerned, but for the most part, these coins have yet to go through any rigerous examination by cryptographers or have any real use on dark markets or any privacy intensive usecase.
