But all the alts, surely like the dotcom bubble vast numbers of the alt coins need to die. It's a world of shit with a few diamonds. And no gaurantees what coins will survie, im sure there needs to be a mass cull in the next few years.
Yeah right.

A lot of us BTC hodlers wish that a lot of the altcoins will die, and many of us, just like you, recognize that almost all of them are overinflated and scams, but if you are betting your BTC stash on some kind of rationality or some kind of purging of shit that "must happen" then you are failing/refusing to accept a decent amount of the irrational reality of the world in which we live.
In this regard, you may be completely logically correct, but you are ignoring actual momentum and other phenomena that affect BTC prices, beyond logic (and beyond simple one cause explanations).
I just refuse to see the simple path to 50k that everone else it seems to see as quite the easy ride.
Stop misconstruing. No one is asserting that the path is going to be without corrections, including acknowledging that BTC prices could go down before up.
I honestly belive 2020 and the rest of 2019 will be the cull years. where countless coins are wiped out, and I honestly think it needs to happen.
Sounds like a stretch, but fair enough. That kind of prediction is not beyond reason, except for the part that such culling "needs to happen," which seems to place too high of a certainty on something that is likely further from certainty than you are making it out to be.
Look at siacoin that i made so much profit on, it acts as a decentrallised cloud server on the blockchain, pays people to store other peoples encrypted data with fail safes. Inginious idea, but still sometihing like only 10 terabytes used, when $150m is invested (or at least the market cap). thats 5 x $50 2TB harddrives.
Who gives any shits? We are talking about bitcoin, not your inability to focus... that causes you to buy shit coins (that may have happen to have been profitable for you).
If you're correct i will bow down, say sorry you were right,
What would I have been right about? I am not asserting anything, except for saying that you seem to be placing too much certainty into outcomes that you would like, which seems to be pretty obviously causing a decent amount of stress upon you.
Im not too proud to admit when im wrong.
Well, you are going to be wrong when you make predictions.. Being wrong comes with the prediction-making territory.
But im convinced this pump is a scam, or at least an effort to avoid a long bear market. I don't buy the "new money" argument.
Well, sure it is possible that this whole upwards price movement that broke above $4,200 on April 1 and has not really significantly corrected for any meaningful amount of time is a fake out or a bull trap...
Seems like a stretch of wishful thinking, and you surely are entitled to having your opinions and speculation about what is going on, even if such scenarios seem a bit far fetched, at least during our current BTC price dynamics - and maybe if BTC prices go below $5k, then I might come to give higher chances to your scenario, but it seems that even now, there is likely to be a decent amount of support between our current price of a bit above $8,400 and $5k.. so it will take a while to get below $5k, if that is where we are going.
