How to Buy Polygon in Japan
Step 1: Register and complete KYC (know your client) verification
Most sign-up processes are relatively straightforward, but you will have to go through the Know Your Customer (KYC) process. Today, almost every exchange in Japan requires its user to verify their identity. The KYC process for users in Japan includes sending a copy of your passport or identity card, as well as a video of yourself, though the exact process varies according to the exchange you've chosen.
Step 2: Fund your account
Once you’ve completed the KYC process, you will have to fund your account. Every exchange is different - some support local fiat payment methods, while others only allow users to deposit cryptocurrency. Beginner-friendly exchanges do their best to have convenient payment methods.
Step 3: Buy Polygon
Once you have a verified account with some funds, you're fully set up. Simply navigate the platform of your choice, find Polygon, and buy it! As you can see, buying Polygon in Japan is relatively easy and can be done quickly and efficiently.
What to do after you’ve bought Polygon?
Once you’ve bought Polygon, if you want to make the most out of it, you still have a couple of decisions to make.
How to safely store your Polygon
Keeping your crypto safe is arguably the most important step of them all. Here you have a few options depending on what you intend to do with the Polygon you’ve bought. If you intend to HODL your Polygon for a long time, you should consider getting a hardware wallet that isn’t connected to the internet for safekeeping. If trading is what’s on your mind, then storing your Polygon on the exchange you’re trading is the easiest way to go. The danger of keeping funds on an exchange is that you or the exchange might get hacked; luckily exchanges like Coinbase and Bitvavo are starting to insure customer accounts against hacks, which somewhat mitigates the risk.
How to stake your Polygon
Staking is a way to earn interest on your Polygon, which can really help grow your crypto holdings over time. If you have chosen an exchange that allows Polygon staking, you can activate staking from the exchange. Often, staking will include locking your Polygon for a certain amount of time, which is risky since the value of your Polygon can drop while it is locked.
