It's heartbreaking that such vulnerability can be found in something like Zcash, after many years since launch, it seems like years after years a new reason why Bitcoin seems like the only safe place keeps popping up.
No Blockchain is safe from vulnerability it seems.
Sorry to all those who trusted and rely more on Zcash.
Bitcoin just feel more like the best bet after all.
At the moment, there is no evidence of that bug exploitation and also no evidence of changing ZEC's supply. There is also a difference between Zcash and Bitcoin. Bitcoin by design is much simpler and more transparent compared to Zcash. Zcash has much better privacy and comes with heavier cryptographic complexity.
Bitcoin is the safest bet in terms of investment and bugs because Bitcoin is the most popular currency with more than a trillion dollars put into its market cap and lots of developers constantly reviewing its code. No coin matches Bitcoin's popularity and market cap, so, yes, in that case, it's the safest bet but it's not the most anonymous cryptocurrency and it's not the most profitable cryptocurrency for holders either, not anymore.
