Political / Legal. The current political attacks being lead by senator Elizabeth Warren and cronies was initiated after being directed by Jamie Dimon (who has since been appointed as the AP or Authorized Participant for the largest BTC ETF). These attackers seem to be doing their very best to legally separate plebs from their sats while aligning Wall Street to become the custodians of our freedom money.
Technical / Social. The L1 Bitcoin network is currently being spammed by Ordinals and Inscriptions which is prematurely increasing the L1 transaction fees. This is pricing out many lower net worth folks from participating in L1 self custody. This attack seems to have a large amount of buy in from NFT pushers and alt coiners as well as a good chunk of the miners as most of the larger miners are being short sighted and looking to maximize profits in dollars as much and as quickly as possible. This has lead to a huge battle within the Bitcoin community and it currently remains to be seen how this will play out.
Wall Street Attacks. By now everyone knows that Wall Street is here as they have had their ETFs green light. If the first two days of trading are any guide of what's to come, then I'm afraid to say its starting to appear they're going to buy OTC and dump spot market in an effort to control the dollar price of Bitcoin. Just look at what Coinbase has said with respect to their reported $7,000,000,000 USD of OTC traded the first day ETFs did. None of course can be independently verified by any of us plebs. These ETF / Wall Street folks are asking us to invert the ethos of "Don't trust, verify." into "Trust us bro." In my view Wall Street would gladly take a substantial loss on these Bitcoin products so long by doing so they believe that it would greatly harm or destroy bitcoin in the process as Bitcoin is the largest threat to their way of life.

I'd say the "biggest attack" on Bitcoin is the approval of spot ETFs on the US and abroad. That's because big institutional investment companies will acquire a large portion of the supply, leaving the "little guy" out of the system. With this move, governments will finally be able to control Bitcoin (sort of). The high network fees are not a problem, since they can be lowered with subsequent network upgrades (subject to the community's approval).
In fact, high fees makes the BTC network stronger over time (prevents spam). You are basically paying a "premium" for transacting on the most secure and reliable payments network in the world. It's the "Wall Street" problem (ETFs, futures trading, etc) that we need to solve. If we don't do anything about it, Bitcoin will ultimately fail in replacing the middleman (eg: banks) for good. Who knows what the future holds for the project?
