What with google, twitter, faceburg and whoever banning all the pump and dump coins it does appear to be having quite an impact on btc and other top crypto. I never got into all those ico as I looked at so many as scams and being the exact opposite of what btc was meant to be but this has changed things quite a bit. I'm not banging the drum saying btc is dead like I'm seeing all over the Internet lately (people have a lot of hate) but due to me not completely understanding the ico market entanglement with btc I misjudged
there is absolutely no "entanglement" whatsoever between ICO market and bitcoin. they may take effect from each other to some extent but it is not that big to even talk about!
what happened was that all these ICO tokens and all the rest of the altcoins were in fact over-pumped and needed to be dumped and come down. that is exactly what has been happening. in fact if you check the history you can see this is perfectly normal that altcoins get pumped then after a while there is a dumping season when they contentiously get dumped.
as for bitcoin the drop was normal at first since the $20k was not a normal price at all. you can even call it a bubble. and then after the drop ended and market was corrected the FUD campaign started and that kept pushing the price down artificially until we entered the bear market.
and we all know whenever bitcoin is having these big moves, everyone else dumps altcoins to get involved with bitcoin.
