Вопрос еще и в стабильности сети.Получается что только 100 делегатов-майнеров будут поддерживать сеть.Маловато будет.
Having a fixed amount of active delegates may result in a less decentralized network. Ideally, the community aspect of the network should fix that issue. If only a small part of the Lisk users vote for delegates this problem becomes worse. In the future the number of active delegates can also be increased, if the demand for it is there.The DPoS variant of Lisk also introduced inflationary forging rewards in order to have an incentive to become a delegate. While this is no real drawback some might have concerns over an inflationary crypto-currency.
Daniel Larimer, founder of BitShares and DPoS, argues that 101 single-purpose servers are more decentralized (and cheaper) than a thousand or so miners on a few mining pools: "Already, Bitcoin is centralized to the point that with just three mining pools, you can control 51% of the network. With just four ASIC chip manufacturers, you can control 90%+ of production of future hashing power".
Vitalik Buterin, founder of Ethereum, calls our type of blockchain a consortium blockchain: "I think it is incorrect to say that [a consortium blockchain] is centralized [..]. Realistically, it is secure enough; it is decentralized enough. And it does provide fairly strong security assurances by itself".
Если вкратце то вполне достаточно. К тому же это намного дешевле и децентрализованнее. Кстати число делегатов может быть увеличено если понадобится.
забейте на yobit, там всего было ~25к монет. После официального старта там сольют до 50к и ниже. 
а блокчейн никуда не денется
