Is possible that coin like THEKEY go to 3 digit number per coin? THEKEY has total supply 10.000.000.000.
Is better to pick coins with lower supply or market cap if you're searcing high price of coin like SHIFT, ATLANT, BREAD?
Almost every coin which has price above 50 $ has low market cap and suppy (NEO, Augur, Decred, Populous...)
What's your opinion?

Of course, in commercial business. In any field if the supply is less than demand, then it is certain that the price of that currency will be high. As in the digital currency market, some coins have lower supply than demand, the price of that altcoin will increase day by day. There are many factors that help you to analyze the good or bad altcoin. Wish you earn lots of coin in the crypto market.
