I do still remember about Decred and here is the answer for the title of this thread:
When you compare a real Iphone with a fake one, the real one will always win. And in this case, Decred was designed to compete with BTC.
BTC definitely will gain more value in the future but Decred probably will only stay as an altcoin for a "mining play".
And when the BTC price hit $200k, DCR price also will rising but how high? perhaps only a few bucks.
The question is, why people need to use Decred while we can use Bitcoin?
it used to be a top coin but seems forgotten already. the current price is $15, checking on its data its more than $100 in the last bull run.
it's a very valid question as to why is there the need to Decred when there is BTC readily for everyone. so why did its price rise so high up to $100 when there is no use case.? i think because the coin is DPOS and anyone who stake will also make profits.
