Do you recommend aspiring investors roll their beastcoins into ingots or keep them liquid?

No one is ever going to share with you their method for making a ton of gil (other than fishing because it's non-competition based vendor gil) because if they did, they wouldn't be able to make gil that way anymore. Anyone on the server who is making gil is doing so because they put in the time and effort to find a good way to make gil. If you also want to make a lot of gil, you will also have to put in the time and effort to do so.

That said, the players on Nas are far from greedy. When I first started I received a ton of help from various people. I have in turn passed that on and help new people whenever I can. If you want an easy way to make reliable gil, I recommend fishing. By the time you get to level 70 fishing you can make 50k/hr easily. I'll paste my fishing leveling guide below.

Nah I believe there is lots of room for expansion on the beastcoin trade. In fact I predict when the bubble burst it will stay at 900+ gil, meanwhile currently it's at 500 gil. Granted when I started it was at 200, but old Orlando Anqtues really drove up demand. I believe he's smelting the coins or using it for something else. But one thing is correct, Orlando seems to have unlimited gil, but for some reason he's not snatching up all the beastcoin, is he banned from AH trading floors? Are the rumors of insider trading true? I can't get straight answer from the Optistery in Windurst Waters. Do you think I can send petition for freedom of information act to the Heaven's Tower?

Fishing will likely work unless it leads to rampant inflation that disturbs Nas.

Then again, a lot of people will be turned off from having to invest the time to get to fishing up there, even if it's a joke to reach compared to retail.

Don't worry I don't think that is likely. Fishing would cause inflation if there were bots for sure, but Nas is good about that. The way it is now if fishing caused inflation then vender fishing would have come less and less worthwhile, and people would quickly stop because their time would be better spent elsewhere. After they stop, inflation returns to normal (assuming the only cause was overfishing) Even as a high-level fisher, you really don't make that much gil. You just make it consistently while brainlessly watching Netflix and drooling. A level 75 THF could vendor much more gil in an hour in SSG.

THF + RDM + pick a craft.

10/10 would read again.
