About mj-fin
mj-fin is a free tool for following crypto markets and your own portfolio, in English and Bangla.
What we do
We show live prices, calculate your real profit and loss, sync your Binance trades with a read-only key, and alert you when prices move.
What we never do
- We never hold your money or your coins.
- We never ask for keys that can trade or withdraw, and we reject them if you try.
- We don’t give investment advice or promise returns.
- We don’t run deposits, “bots” or referral payouts.
How we keep it safe
Passwords are hashed with Argon2, exchange keys are encrypted, sign-in supports two-factor codes, and the service had an independent security review before launch.
