Pascalcoin is the most functionally scalable cryptocurrency currently available. It is capable of handling over ONE MILLION transactions per second as it is already designed and released (not a testing technology or to be released in the future). For reference, VISA currently handles about 2000 transactions per second. Pascalcoin has gone under the radar for most people. While many ICO’s are going on today starting with market caps of $60M-$100M with little more than promises, Pascalcoin stands apart with a well functioning, tested, scalable blockchain. With a micro market cap of only ~$9M, it stands out as undervalued to me, but, as always, do your own research and make your own decisions.
Here’s a link to their video too which also explains it pretty well: https://www.youtube.com/watch?v=F25UU-0W9Dk
