Paypex is using their token PAYX to power their platform through the use of smart contracts on the Ethereum network and basically what they want to accomplish is to address the needs of money transfers in a peer-to-peer system.
Paypex investment is a good one, this is mostly because they are simplifying the concept of cryptocurrencies for daily payments and usages on a peer to peer platform with no fees attached whatsoever. This has a natural tendency to attract investors attention and improve the platform’s performance.
Unlike most traditional payment gateways, the enormous fee charges on transactions are sometimes ridiculous, and thanks to decentralized products like this, digital asset users can confidently rely on the generic peer-to-peer model of business activities without interference from the high cost of transaction processing fees.
The good thing is that they will be at the cross point for all systems needing transactional throughput to include service providers, fraud management systems and other cryptocurrency dependent gateways.
To buy Paypex token at the time of this writing might be a bit of a challenge as there are not so many exchange markets currently trading it and more so, the only two exchanges that are trading it are doing so with the ETH pair only. More so, the exchanges are not so popular and might give newbies a tough time.
Unfortunately, this means that when you want to buy PAYX, you would have to sign up on either one of these two particular exchanges if you are not already registered with them and you can ONLY buy using ETH. If you do not already have ETH, you may have to deal with the stress of exchanging BTC or other alt cryptocurrencies to ETH before sending to the exchange and the accompanying transaction fees too might be a biggie.
As for storage options, you are limited to myetherwallet and mist, since PAYX is an Ethereum based asset.
