This is one fun and profitable way to earn Linden Dollar in Second Life, just by yourself.
To crack it down, you need to collect items which have a certain value. The good thing about Rise Hunting is, that a lot of sim owners uses it to get traffic for their sim and it’s surely fun to hide the items.
I earned in one month around 4k L$, but not even playing that much. If you would keep checking all the time if somewhere of these Items respawn you would get a lot more Money.
