Earlier today i got to know about Five different questions you have to ask before Investing in a Blockchain Company. I think investors should note this. Thanks
The questions are;
1.Does the blockchain have an earnable token?
2.How will data get into the blockchain?
3.Does this require a consortium to agree to its use?
4.How will the data be analyzed and used?
5.Does the blockchain perform at the speed of business?
The blockchain is working on the distributed ledger system and that depends on how kind of system has been used by the blockchain itself. If the blockchain use POW and you can earn coin from there by mining and if blockchain use POS and you can earn through staking.
Blockchain will be contributing a lot as long as it can provide a better scalability and blockchain has a chance to reduce the operational cost for mainstream companies.
