Altcoins like EMAX lack the stability of older types of cryptocurrencies, like bitcoin and ether. And EMAX has never reached meteoric highs like bitcoin has: At its peak in November, bitcoin was worth about $69,000 a coin, while EMAX hit a peak that equated to $0.000000051 shortly after its launch, according to CoinMarketCap. Some of the technologies we use are necessary for critical functions like security and site integrity, account authentication, security and privacy preferences, internal site usage and maintenance data, and to make the site work correctly for browsing and transactions. Ethereum Max EMAX official smart contract address is 0x52e50dac43425e9e568475305c252ae48df8ff1e. The downside is that performance issues arise because every node calculates all the smart contracts in real-time. As of January 2016, the Ethereum protocol could process about 25 transactions per second this did not change after the proof-of-stake implementation. In comparison, the Visa payment platform processes 45,000 payments per second. This has led some to question the scalability of Ethereum.
