Today, most guys that work with crypto associate DApps with Ethereum. DApps are the applications that are resistant to most hackers' attacks, and the blockchain is the basis for them. They can be even used in gambling and gaming like in the case with Tera Foundation https://terafoundation.org/. Tera Dapps are cool for business connected with Smart Contracts, and for trading as well https://terawallet.org/dapp/20#TabTrade. They work on JavaScript, and not on Ether.

Tera Coin mining is very profitable as the block foundation takes a second only. The algorithm is unique in that the mining of coins occurs due to CPU-capacities with a bias on the use of RAM. Besides, when you get Tera tokens, you can "turn" them into other alts easily as they are supported in over 11 exchanges.
