thank you all answering and i have better understanding as i don't want to make any expensive mistake.

i have a final question; i did some research and came up with fake btc transactions;

so if i receive 1BTC to my Trust wallet, and verify that transaction through blockchain explorer, and have at least 3 confirmation;
is that btc balance and or transaction on the blockchain can be faked?
is it possible to send some other shit-coin to my btc wallet and appear as a BTC but it is not transferable or usable
thank you
