I still remember when the token was 2 cents but I didn't buy any because the team only consisted of 3 people back then, the ico didn't do well and Bruno Block was anonymous. Oyster jumped from 2 cents on 12/11 to ath of $4.80 on 01/07/2018. Less than 1 month. With $10k, you could have bought 500,000 pearls and became a millionaire in under 1 month.
I still believe in the project. They rebranded, released a testnet, hired Chris Gardner as new CMO, etc. If they wanted to take the money and run, they could have done it in December/Jan. But they didn't and it's April.
And what if Bruno Block is Satoshi Nakamoto?
I also hold the opinion that the project is serious. It is evident that the guys are working on development. This is one of the most successful of my investments, so I prefer not to trust rumors, especially since for every word of these rumors, there is a sane response from the team.
