this is link to wordcoin? so why there ticker is 607f?
It's not officially listed so it gets its ticker from the first letters in the contract address (0x607fb630f2ddf7aeb1a207d7cb6ba6ec9f10c308). If you have doubts, you can check that it list correctly the amount of wordcoins you already have in your wallet.
Oh thank you now I got that. Now I try to add custom token in my mew. How much decimals should I point?
