carding bitcoin?

[mustalain]

so far i have basically only seen carding as a secure way to gain access to an account and buy random products with it like $500 phone or something.(i might be looking at some outdated random sheiz but like..). only to just sell the product and gain the cash. but why not just buy bitcoin...? and if you do buy bitcoin does that also mean that the bitcoin will need to be mixed? like will authority's even go as far as tracking the purchased bitcoin through the blockchain?
idk why it continues to be a long process, even after gaining full with some form of a bitcoin exchange site. after that it should just be as simple as using the card to exchange $500 or whatever to bitcoin and transferring it to a different address (your own) is that was is traceable? are there workarounds such as these blatant bitcoin mixers on hidden wiki??
thank you,
