He's already addressed the third party stuff, and complaining about whales getting a lot more than people who don't wager very much is just....dumb.  They have daily roll hunts with 0 wager required, tons of weekly promotions that require 5 and 10 cent minimum bets, all the bonuses that the whales get the are based directly on how much they wager.  If you want bigger bonuses, wager more. It's a casino not a charity.

I'm with both of you for Gate Of Olympus, IMO just the same like Shitty Lolipop Bonanza ~XD

But, for IRON Bank I disagree comparing to slot on the tops more prefer to Iron Bank the game have different option bonus future. I gues most people who rekt on Iron Bank because they want to chase a high multiplier by choose on the middle bonus. I more prefer on left not really big multiplier, the big multi but not make you rekt so much too ~XD

AFAIK, buying spins on the slots seems safer option because mostly I love to watch the spin based slots on the live which is kind of enthusiastic to watch and $300 maybe a small amount for the risk you took because people spend thousands of dollars and get the same in return is what I had expereinced.

Had experience with other slots as well but everything was unlucky on my side what I wanted to say is when you are going through spins you may have the chance of hitting the bonus on the final slots as well but yeah the risk is more for the returns but in my opinion, it looks better because you still have the chance which keeps telling on your mind.

I'm wondering, do you even play at Stake and do you check all the available offers there (not only on the website but also on the forum and other social media)?
Saying that Stake is ignoring small players is completely wrong. I'm not a whale but I get something great in return at Stake, at least something that I cant get on other places.
Should I mention what are the offers? Reload, weekly bonus, monthly bonus,forum challenge, telegram challenge, special event bonus.
All these bonus are available for all players (not only whales) but you cant complain about the value/amount of each bonus.
It is logic when a casino gives higher bonus to those who wager more because these players are risking more money than small players.
If they do not care about small players, they wont have all offers available to all players.

Just. Use. Another. Coin.

LTC - 8 cents
TRX - 6 cents
EOS - 35 cents
DOGE - 7 cents
XRP or BCH - less than a cent
ETH - $12
BTC - $13

Arent you aware that there's still none who had been using up your service? Because simply no one would ever trust it.

Stake does have internal exchange which you can make use if a certain coin is having some problems with high fees.
Dinabot is a common one.

I can't see why anyone would use your service based on trusting someone not being a mixing service with their send, is all I can come up with off the top of my head.
Why wouldn't they just use another altcoin such as tron, ripple, litecoin or even dogecoin for that matter to do their own withdrawals?
If they don't have those coins which are available on the site, then they can just use the site's own internal service to exchange their currency into those coins so to initiate a withdrawal.
That's what it is there for. So they don't have a mob situation towards their live support representatives receiving messages saying they were scammed. Such as what has happened in the past on the site. From what I remember it happening a year or so ago. When they had private chat session available between users still enabled. But have since stopped it due to lending and possibly this very same thing happening asking for withdrawal services.
Just mentioning and not assuming this is what your doing.

In 100 manual spins we don't necessarily get the jackpot , In this formula we already know that there is only a 1:100 chance of winning
That's only 100 spins so what about 200, 300 or 500 spins? then don't be surprised if we lose $300 in 10 minutes that's normal  
In gambling there is definitely more to lose than to win If this situation is reversed, of course we will not be able to see the gambling site go bankrupt
