You could make your own sort of "encryption algorithm" just so if ever someone gets a glimpse over your seed, they wouldn't be able to steal your coins. Like, probably instead of writing your seed straight on, probably take a look at the word list and list the words above or under your seed words instead. This example is definitely not a good way to do it, but I hope you get the idea.

This is definitely a bad bad way of doing it.

Actually, that's a smart contract that when you send any amount ng ether sa address na yun is auto send siya sa main eth address ng hacker/suspect. If sino may eth address ngayong using coins.ph, yan ang gamit nila.
In million users ng coins.ph pag mag send sila nh ether sa ether address na andun sa account nila then auto send yun sa main address ng coins but yung balance/numbers of ether will be stored in their account.

Kaya be aware sa mga ganyan. Always remember na walang easy money.
