I get your frustration, I actually think a lot of us are. Try to keep in mind we're all on the same team here, we're all rooting for XRP and we're all trying to make some profit here and there.
With regard to your post, I'd like to say a few things by breaking it down to a few categories:
BTC's performance since (roughly) March 2019
It's perfectly normal for BTC to go up first. You may or may not like BTC, but in order for Altcoins to pump, we need BTC to be big and strong. Ultimately, value will flow to some (!) Altcoins. Pay attention here, as I am jumping to the next point.
XRP's performance over the course of 2019 thusfar
You're clearly frustrated by XRP's performace, and I get it, XRP's performance has been absolute **** over the course of year or so. We've had tremendous news, which would have caused the price to go absolutely mental during a bull run. Nevertheless, Altcoin season hasn't started yet, and it remains to be seen when it will start. I am not going to debate on the matter if it will start. I do believe there will be another Altcoin season some time in the future, but it could be next week, next month, next year or it might take another 5-10 years.
XRP's performance in comparison to other top 10 cryptocurrencies
Unfortunately, I don't have a definite answer on this question, as I am as well quite baffled by XRP's performance in comparison to other currencies. There's theories going round on this forum about members of the Ripple team selling large portions of XRP, effectively keeping the price on a low level. I even consider the possibility of the existence of large bag BTC holders with the sole purpose of destroying XRP with everything they have. More likely, however, is a lack of demand which causes the price to remain low/be stagnant. As I said, I would like to give you an answer but I am guessing just as much as you are.
BTC is going to crash back to 5k (or lower), XRP will be in the sewer (or it might already be there, depending on who you ask)
It could very well crash back to 5k or even lower, one would be a fool to deny that. If this were to happen, it will implode the cryptocurrency space (including XRP).
XRP should have be 5, 10, 50 or even 100 dollars by the end of last year
My final thoughts: stay far (and I mean really far) from all the crypto YouTubers, 589-preachers and bearable guy-adorers. Nearly all of them are full of crap and spread more hopium than your local pusherman. I personally believe XRP will do well in the future, but it will take a lot of time and those predictions you mentioned are way off (IMO). Stay with your feet on the ground and don't get emotionally attached to your investment, it will lead to bad decisions.
