Raspberry pi 4 2gb/4gb

I saw the other day that raspberry pi  lowered cost for  raspberry pi 4, 2 gb version to 35 usd.

So my thoughts were to get a pi 4 , upgrading vpn to dedicated  ip.

What you guys think, the 2 gb version strong enough  to be able to run a sanctuary ?

With the transition to add Monero along with Bible pay, it may work for a while, but not for long term.  I mined Monero with the Raspberry Pi 3b+ and it never gave me coin.  I would suggest making them mine together but not as a sanctuary.
