The Raiden project has been touted to be the ‘lightning’ network for the Ethereum blockchain, such that it will function just as the lightning solution for the bitcoin blockchain is expected. The platform is designed for off-line purposes which sync with the online system of the Ethereum network to ensure that transactions are scalable even during high traffic.
Mainstream usage for decentralized products in the case of micropayments is still a long way from the current setup of most infrastructures. Most people would agree that the major problem with blockchain is scalability and that’s what this project is about.
Scalability comes into play when the design is tested to host a couple of transactions down the mainstream without breakdown nor downtime. Raiden investment is making a break for the accelerated adoption of cryptocurrencies like ETH for micropayments and possible put such currencies ahead and most preferred and making decentralized financial platforms the ultimate gateway for such payment solutions.
This coin is an ERC20 compliant token and is currently traded on over 10 exchanges, which makes it quite popular as it can be traded with BNB, or with BTC, ETH, USDT, and even USD as FIAT.
Chances are that you are already registered on one of the exchanges where the token is currently being traded and you would not need to register a new account (especially if you are an active trader). However, it should interest you to know that BTC has the largest trade volume across most exchanges followed by ETH, so it should be easy for you to buy Raiden token by exchanging another crypto asset to BTC before trading it for RDN.
Since the token is an ERC20 type, you can store it in your myetherwallet, metamask or any other compatible wallet where you can guarantee that you control your own private keys. You could also try the hardware tokens like Trezor and Ledger Nano.
