PCHAIN is yet another type of build your project on top of our blockchain scheme. This one, however, does have an interesting twist. They allow for cross chain smart contracts. This means that the contracts produced on PAI can actually be used on other more popular chains such as Bitcoin or Ethereum if they prove useful. They also address the common issues Ethereum has such as instituting sharding to help with scaling their platform and making "smarter" smart contracts.
There's only one problem with your PCHAIN investment, there is no working product here and there won't be for some time. It's all well and good to say you have the best solution to Ethereum's woes, but you don't really if they are not yet created. All of these great things are still theoretical, and it's possible that by the time these solutions are implemented that Ethereum will have already fixed their own issues.
For most of these build your apps on our blockchain projects, this will likely be a death sentence. Once Ethereum is up to snuff and can handle the onslaught of transactions applications will be throwing at it, there will be little reason to use any of these secondary solutions.
The selection of exchanges where you can buy PCHAIN is not great, and the options are a little unusual. However, the trading volume is excellent, and investors interested in this asset will be able to quickly and easily execute a trade here without much trouble. Ethereum is the most viable trading pair as it holds the most liquidity, but there's also a good amount of volume in Bitcoin as well if you'd prefer to utilize that pair.
This is an ERC20 token, investors interested in finding a safe place to store their assets will need to look for a reputable Ethereum wallet to do so. There's a ton of options here. If you'd prefer a mobile wallet option then Coinomi and Jaxx are great solutions. If you'd prefer a hardware wallet, then you can look to Ledger or Trezor as a solution. In any case, make sure to back up your wallet seed in a safe place in the event that you need to restore your wallet. If your host device is lost, damaged or stolen, this will be the only way for you to regain access to your funds.
