Lump Sum, DCA or other Investment Strategies?

Long-time lurker here. I recently inherited €70,000 and plan to invest it all into Bitcoin over the next year or two. I’ve been DCAing small amounts for a while but this is a larger sum.

For context: I sold my car and moved to a walkable city last year, so this money is my “future fund.” I’m risk-aware but don’t want to gamble. My plan is to spread buys over 12-24 months, but I'm looking for some input here.

Everyone says “just DCA and hold,” but are there actually better methods for larger sums? I'm especially worried about entering at this point in the market with a lump sum for example.

Also, what exchanges are the go-to for Europeans? I keep hearing horror stories about withdrawals getting frozen.

No ego here, roast my plan if needed. Just don’t want to regret this in 5 years. Thanks for the wisdom.
