I could see that you are very supportive for Bitcoins. We are all trying to be optimistic. Thanks for helping!
Everyone should be optimistic though the market has been on the bear market until now.
You have to encourage and be optimistic, if you will be like those people who are very skeptic and their pessmistic ideas are coming in you won't grow and you're no longer interested on the future of bitcoin. But we have the same goals here and that is to see the great price of bitcoin.
$30,000 - $50,000 is ideal for 2019.
But I think being blindly optimistic is also setting yourself up for disappointment. What if bitcoin never gets to those highs again. Sure, we all want bitcoin to be worth $20-50k, but that's just wishful thinking. Realistically is that going to happen? Probably not. Call me skeptical or pessimistic if you want but I'd rather be realistic about things than just baselessly speculating on these magic multiple tens of thousands of dollar numbers.
