One of the most important factors for a stablecoin is its stability. It is not enough to be backed by another asset, as there are many situations in which the price of this stablecoin can rise or fall.
However, this can be solved by having a large amount of support. This is what makes crypto whales so important in the crypto space.
The cryptocurrency market is a volatile place and a lot of traders flock to the biggest exchanges that are most likely to make a quick buck. For example, in December 2018, Bitfinex suffered a cyber attack that resulted in the loss of $60 million in crypto.
However, some whales have so much money that they can be patient and wait for the right moment to act. The most famous example is that of Mark Zuckerberg, who bought Facebook for an initial price of $38 and sold it for $104 billion.
