A little introduction about the three cryptocurrencies OP is talking about.
NEAR:
NEAR Protocol is a decentralized application (dApp) platform and Ethereum competitor that focuses on developer and user-friendliness. Its native NEAR tokens are used to pay for transaction fees and storage on the Near crypto platform.
The Sandbox
SAND is the native cryptocurrency of The Sandbox; a popular 3D "metaverse" game built on the Ethereum network that users can explore, purchase land on and create structures that can be monetized. All items acquired in The Sandbox are 100% owned by the players themselves, creating revenue opportunities for gamers.
Moonbeam
Moonbeam is a crypto token based on the Polkadot blockchain. Polkadot allows users to create their own blockchains, called parachains, which are linked to Polkadot's main relay chain. The idea behind Moonbeam is that, while it operates on Polkadot, it is able to connect to and interact with the Ethereum blockchain
.
Looking at those three, I think Near is pretty much ambitious, but I would say the project is much more promising than the other two. In terms of the price ratio from its all-time low to current price, I think Moonbeam is very much to give more profit when the market boom since it has grown around 23% from its all-time low price. In terms of active development NEAR Protocol beats the two. I leaned on the developers activity so I can say among the 3 Near Protocol is a good catch for investment.
