Its simple herd mentality and fear.  If you want to believe its some large "whales" who happen to hold lots of altcoins and dump everything at the same time, then i have a bridge to sell you.  Its simply hundred or thousands of people reacting to some trigger and then following everyone elses move to sell, or simply not buy.  Just the same as when everything rises, lots of people buy and few sell so prices rise, even though there's been no real change to the outlook.

I would have got involved, but KYC system broken, was white listed but wouldn't accept my login, no support response in days so missed the boat now.

iirc in regular futures markets, the expiry tends to see a rise as positions are closed and people buy to cover short positions.  But the BTC instruments are options, settled in cash, so there's no need to trade the asset directly. 

Cancer is very undeserving term.  You overlook that they have created the high prices you enjoy. Take the rough with the smooth.

Shame you didn't tell us about this last Thursday 

Maybe you invest in regulated assets instead?

This is certainly good news and each change like this is usually followed in spirit by other major nations, if they dont already cover the same area.  Next China authorizing mining under license?

That assessment is not necessarily correct.  You can sell up a number of positions on exchange and move a single transaction, while when buying may have made numerous smaller transactions over time.  Also people moving away from Bitcoin to ETH/LTC/BCH for moving funds between exchange and on/off ramps. All the mempool tells us is Bitcoin is being used less.

Shade and fans for airflow.  Operating temperature for a GPU is quite high, you need to put enough cooler air across them to keep them in range.  Even if the air is 40deg C, if you blow enough it'll keep at 60-70deg.  Just need an a lot of fan power.  Maybe its not that simple, but i can see how some clever engineering could make desert mining viable to take advantage of the abundant daytime power... however batteries for sustained overnight running is the bigger issue imo.

I'm apprehensive.  Take a look at a all time chart for the Nasdaq, look at 2000, and if you dont see the parallels with Bitcoin price then good luck to you.  Sustained drop below 10k signals a fall to ~8k if not all the way through to ~6k, theres.  Some individual crypto will do OK, hold major crypto for the long (as in proper long, not crypto long) term, but now probably isn't a time to invest new cash.  

Icobench is certainly one of the better for presentation, but they miss a lot stuff (that hasnt paid for review?). Same for Icorating, best presentation imo but headlines with those that pay for reports.  icodrops is good, icoalert is good coverage but a over engineered UI.  And there are others, I've yet to find a comprehensive one that covers all reliably.

Maybe you have a look at the Github repo?  There's one regular contributor and maybe 2-3 others. Very few updates, when i last looked end of last week there hadn't been any for 2 days.  Announcements for team members joining recent dont impress or cover the fact this project went to market with a real team involved.  Justin Sun himself is no developer, graduate in history.  He's a manager and marketeer, maybe a damn fine one, but certainly no CS engineer.

Oh yes, and that Ripple connection, a Chief Representative for the same period he was chairman and CEO building Peiwo?  The man must never sleep, like to have a couple projects on the go and will probably get bored of Tron before it delivers.

Wrong answer. Its not about this coin, I could have picked any of a number of recent market entrants, they just happen to be notable today. 
Everyday people push their favorite thing as next big thing, yet they repeatedly miss the next big thing. Its just funny.

There is a lot of cake in the cake shop and we certainly cant eat it all.  This cake is moist chocolate cake with Belgian chocolate ganache, hidden away while people rave about own brand sponge cake, muffins and some times a lemon drizzle cake. Fine as they are, people in the know should be knowing about the top notch fare, apparently they only know the basic common choices.

Odd, why close two of the largest and oldest markets?  Making a dedicated platform might itself make sense, but transition should be in parallel for a few weeks at least. 

I think they already have, just the community didn't want to believe them so they stepped back into the shadows.

What is SIRIN LABS Token?  I'll tell you what it is, yet another token that does blockchain, p2p and smart phone stuff, that raised $157m,  and just popped into top 100 market.  Never heard of it.  All the "where to invest" "whats the best ICO" for two months and I cant say I've seen a mention of it.  True there are a lot of coins mentioned, but one would expect a big deal like that to be more prominent.

So I conclude, this forum knows nothing. 

Coinbase will verify eventually (unless you are saying you can submit details?).  Also look at CEX.io for depositing.  I'd like to recommend Btistamp, but been waiting on them weeks myself.  You may also consider localbitcoins, though i myself am reluctant to deal £'000 with blokes down the boozer/coffee shop, ymmv.  Look up about using Revolut to deposit via Euro's and more importantly withdraw.  There's an effective blockade against Bitcoin/GBP conversion, which is very odd considering how many operations are in the UK, you're fine if you step through via euro accounts (but tell the bank to avoid account freezes).

Dont invest a lot unless you understand the risk, only put in what you expect to lose.  £50k could be £500k by the end of the year, but it could be £25k by next Tuesday.  That said, buy into ETH or LTC, not bitcoin, to get lower fees and ease entry into high profile ICOs (nearly always ETH tokens).

I use KYC as a good sanity check.  If they are asking for it they are either in a regulated environment and comply with law (good), or a scam harvesting ids (very bad).  If you do enough research to exclude the second option, you're left with a good story.  

Just the same as holding shares, while they sit there on account/paper certificates, the value can ballon and no tax is collected.  Sell them and tax is due.  Bitcoin is no different.  Governments really aren't as concern about this as people think, because the tax system already covers them.

Who is "they".  Government or conspiracy theorists?  Or you going in double, government controlled conspiracy theorists.  Its all a psyops mission man!.

lol, talk about Bitcoin being government created/controlled or from aliens is as old as Bitcoin, its standard for the CT nutters to claim everything is part of the hidden world of agendas by mysterious powers.
