If people are not aware there will be soon new sets with necklaces and rings requiring 2 practoniums ( best in slot depending builds) so the price of the practonium will skyrocket after this update.
Lot of people had 10-15 alts that are saalus slaves + roll mystic cube everyday so end up having tons of practonium and fast.
Also to make easy silvers, you can try a wizard 2 linker 3 thaumaturge 2 featherfoot 1/2 just run 260 dungeon + swell body on 10 linked monsters and rush. It’s very very fast and easier than the scout 3 170 farming with bad weapon for example.
