what makes some btc coin's wallet addresses start with bc instead of 1?

[plzdontlaugh]

it looks like it follows the coin through every dif. trans. couldnt coins be tracked like this?
the coin was bought through libertyX, ive never noticed it before
anyone know? its not btc cash either regular btc

there are currently 3 different address formats used in bitcoin.
P2PKH addresses which start with 1 which are the oldest and most common addresses used. the transactions are using a pubkey hash to pay to.
there are P2SH addresses which start with 3 which are using pay to script hash. they mostly are multi signatures but SegWit can also have addresses starting with 3.
and finally the newest format is Bech32 where addresses will start with bc1. these represent SegWit addresses.

hopefully this answers your question. I don't quite understand what you mean by "tracked".

Bitcoins can always be tracked, but as addresses are anonymous and shouldn't be reused, it should be difficult to identify users. Read about anonymity at https://en.bitcoin.it/wiki/Anonymity.
