As you know, Tekashi became the star witness in his 2018 RICO case by testifying against his fellow gang member buddies ... which resulted in their conviction.

Tekashi argues it all boils down to loyalty -- or a lack thereof. He makes a decent point about beefing with just about everyone from coast-to-coast and ultimately being targeted by his own crew in what amounted to a scary stick-up job.

You'll recall ... Tekashi was kidnapped by his own security team in the summer of 2018 -- part of which was captured on dashcam video and surveillance footage. He was taken for a ride around the block, where he was threatened at gunpoint, and ordered to fork over cash and jewels he had at his NYC pad ... an exchange ultimately carried out by his then-GF.

In light of that, 6ix9ine explains he doesn't owe anything to those guys ... and even suggests what he did was wise. The Nine Trey Bloods almost certainly feel differently.

Of course, we also had to ask how he's holding up these days, and whether he fears for his life now that he's labeled a traitor with a violent gang. Fact is ... Tekashi was looking over his shoulder when the subject was raised ... but it ain't for the reason you'd think.
