$20 million for airdrop? That is a huge one, but I wonder, instead of giving it away, why not use it to develop and market BFG better? That is a huge money when used properly can gain traction towards the platform. It can indeed fuel people into playing to Betfury, but after that what comes next? People who receive rewards in BFG will surely sell them making the price crash due to the sudden influx of tokens. I do not know if management has seen this before they execute this airdrop. Remember the market is affected by supply and demand, I hope this airdrop is worth the expenses for BFG.
It's worth noting that the Betfury team hasn't forgotten about the development of the BFG token. At least they announced updated tokenomics at the beginning of this year, which further positively affected the BFG price.
As for the Cryptodrop event, I think the influx of new audiences on the Betfury site will compensate them for its cost. At least I doubt that the Betfury team would hold an event with such a large prize pool if they were not sure of the result and the profit they can get in the future. Most likely their marketing team calculated everything in advance.
