The miner has already been sold to immolated. And yes, profit is down now since the bitcoin price has seen a severe dip, but I do not expect it to last long.
No, that's not true, profit is not down because of bitcoin price drop, but because of diff rise, and diff will be still rising
L3+ gives arround 0.00476933 BTC
Current exchange rate : 1 BTC = 3783 USD
Let's say 1 BTC will be back to 4500 USD
So L3+ will give 0.00476933 * 4500 = 21,461985 USD Still very far from the supposed 34 Euros
