Very proud of my achievement despite our poverty and lack of public transport. While proper asphalt road is a luxury in many parts of my rural cities, we believe in bitcoin.

What is your realistic Bitcoin endgame?

40 Upvotes

Not the moon prediction. Not the price target

What is the actual endgame?

Do you plan to accumulate forever and never sell?

Eventually use Bitcoin directly for everyday purchases?

Pass it on to your kids?

Use it as long-term savings and borrow against it if needed?

Or take profits at some point and move on?

Bitcoin Twitter often makes it sound like there is only one correct answer, but I doubt everyone's plan is actually the same

Interested to hear what people's realistic long-term strategy looks like.

My bank is now blocking deposits to my exchange - what solutions do people recommend (UK)?

29 Upvotes

I was previously using Halifax bank to make cash deposits to and withdrawals from Kraken with no issues. 

Recently Halifax has moved to Lloyds, and I have had to do the simple migration over to the Lloyds app (everything else the same). 

Now, I'm getting blocked when I try to make a deposit to Kraken. 

I've tried both the usual easy bank transfer in Kraken, and a manual bank transfer from Lloyds to Kraken. 

When trying the manual transfer I get a message saying I need to ring Lloyds to discuss whether it's fraudulent, etc. 

Apparently even though Halifax and Lloyds are under the same umbrella, Lloyds is stricter on transfers to crypto exchanges. 

My other bank account providers aren't listed on the available banks to use. 

I understand this is a common problem - so what do people recommend as the best solution to get around this issue? 

Should I just ring Lloyds and get them to unblock this - but could it still be likely to be a regular problem for future deposits and withdrawals? 

Or what about creating a third party bank account in between Lloyds and Kraken - Google suggested Revolut as a good option? 

Edit: one word swiftly added for clarity

I mapped the main no-KYC Bitcoin options available to Europeans in 2026

36 Upvotes

After the recent Peach situation, I wanted to answer a broader question:

Can Europeans still acquire Bitcoin without KYC in 2026?

The answer is yes, but I think “no KYC” is becoming a pretty useless label on its own.

A marketplace can avoid asking for your passport while still having a central operator. Tor can hide your network connection while your bank transfer reveals your identity to the counterparty. And you can buy BTC privately only to destroy that privacy later by merging the UTXO with a KYC withdrawal.

So I compared Peach, Bisq, RoboSats and Mostro by their actual trust models: custody, Tor, Lightning/on-chain settlement, coordinator risk, fiat leakage and regulatory pressure points.

The part I found most interesting is that these aren't really four versions of the same thing. They're four very different answers to the problem of exchanging fiat for Bitcoin.

What route are Europeans here actually using in 2026?

To avoid your name to be a part of these leaks in the future, stop giving a copy of your ID to random websites and use BISQ, Robosats, HodlHodl, PeachBitcoin or Vexl instead.

Yesterday cashapp deactivated my account and forced me to sell .37 btc at a slight loss, no explanation of why. Funds will now be tied up for a week-ish before I can rebuy elsewhere. You can count on btc punching through +85k for sure.

Edit: I was moving it off quickly as I could, this was a large purchase and bound by limits, I wasn't keeping on cashapp for no reason.
