Blockchain is the greatest invention , but in my county Philippines, it is used as a means to fool people by scamming,  almost 100 million pesos was taken away to individuals with those staffs,  and now they are in jail,  the only knowledge that i can share is do not invest into some project if you don't know if it is legit and most important, study first what is blockchain. Crypto wiki app in playstore can help even just a little. 

And also do not support blockchain centralization. It is better as decentralized.
