Does anyone know where all the amounts of Holy Powders arecoming from?

Im just wondering where they are coming from? I see Legend cards in the bazaar for around 1000 HP, and am just thinking that its impossible to get those much even if you farm multiple accounts. I even wonder if they get sold in the end.

Lets say you can continuously create new accounts in order to feed your main account. You would be limited because:
1. there is a 2 week wait period
2. you only get personal HP and CW for the first 20 levels. and even after that, it would take a VERY LONG time and ALOT of accounts to gather up Holy Powders in the 100s and 1000s. Do people really have that much time? Because even if you do have the time, it wouldnt be worth the effort....
3. the multiple bazaar systems sometimes lower the chances of trading through accounts.

Now i understand that HP can come from events and Holy wars, but you really dont get much from them, and most definitely nowhere near even the 100s unless you rank near the top and get the SSR card (selling them afterwords). Even if someone pulls a SR or and SSR and sells it for a profit, another question can be asked to where the buyer got the HP to buy the card. Not to mention people selling HP for $0.40 in real money on some sites. (where do they even get so much). I really doubt that people are going to the store and [censored] 100 mobacoins for 1 HP. Or buying packs that sometimes have offers that give out CW instead. I used to wonder if there are large amounts of hackers in the game generating HP and CW in large amounts, but then I also knew that there were people willing to [censored] $500 for a batraz, who might as well hack too. If anyone reading this has alot of HP (as in the hundreds), could you enlighten me on how you got so much? or how you got to the position you are at? thanks...
