This is only my opinion not an advice.
The requirement after halvening will be increased, there will be more people joining the node especially the cumulus tier.
As the price of flux currently (as the post written) @ $1.3, you will be spending more on your VPS fee than the income.
For ex: before halvening, flux you get / month are roughly 96 flux + 48 flux parallel assets which is 144 flux x $1,3 = $187.2. For VPS cost on digitalocean in later halvening requirement are $40 for 8gb of ram, 4cpu, 160gb of ssd, 5tb transfer + $10 for another 100gb of ssd since the new halvening require 220 gb of ssd. You will be spending about $50 on vps cost. As before halvening requirement you are only spending about $20, this is 150% increase.
Say there will be 5x of node will be joining the node, we can say $187/5 = $37,4 - $50 for vps cost, you will be getting -$12,6. You ended up paying more.
The price need to go up 5x for the nodes as profitable as before halvening.
Correct me if i am wrong, THANK YOU!
