Ditto.  I've never been presented with a Captcha on Bittrex.

If you do a little research on Poloniex, you'll really get worried.  The company phone number is voicemail only and the address is just a front.  Go ahead and visit the "office"; there's no Poloniex office there.  The company attorney does not work for the large international firm he claims to work for and never has.  They have never heard of him.  His phone number is disconnected and his license to practice law doesn't exist.  Neither Tristan D'Agosta nor any of the company execs are reachable either.  They have no office number and their personal numbers have been disconnected.  In fact, the personal numbers for all of Tristan D'Agosta's family members have been disconnected as well.  Even the Rutgers department that his mom used to head up has had its number disconnected.  His "best friends" from college claim to have never even heard of him and, interestingly, Tristan is not in a single photo with his "best friends."  For now, I am not concerned because Tristan makes too much money to pack up and take off.  When the US gov't cracks down on exchanges though, don't be surprised if Poloniex goes up in smoke and takes everyone's funds with them.  A legitimate company doesn't use fake lawyers, a fake address and have the phone numbers of everyone with any attachment to the company or its employees disconnected.

Buyer A uses BTC to buy Bitconnect Coin (BCC), which is traded almost exclusively on BCC's own exchange. Buyer B buys BCC and his money is used to pay Buyer A. Buyer C buys BCC and his money is used to pay Buyer B. When the supply of new investors eventually dries up, the whole thing will collapse and those at the end of the chain will be left with a worthless token. This is the very definition of a Ponzi/MLM scheme.

Good catch.  Not buying their response.

It will, literally, never happen.  LTC didn't go up this year by chance.  Charlie Lee's return, SegWit, Lightning Network, atomic swaps, CNBC feature (calling it a "must own"), etc.  It will be over $100 shortly and will see $300 by 2019.

People have been saying LTC is going to die for years.  It isn't happening.  There are ATMs in Canada.  Coinbase has now added to its app.  It is being offered via retirement funds.  Charlie Lee has been working hard and it has skyrocket ever since he returned to it FT.  $100 by end of this year.  Heck, maybe by end of September.  $300 by close of next year.  Mark this post and feel free to come back and mock me if I'm wrong.

Poloniex has about $10K of my money and I am unable to get it out of the exchange.  Moreover, I have proof someone inside the company is engaging in insider trading and manipulating the market.  Poloniex doesn't respond to tickets.   

OP, I agree.  NXT's price chart has all the makings of a P&D coin.  The crypto market is, inherently, volatile, but no legitimate coin goes up and down 50-60% every few days to weeks (and then repeats the cycle again and again).

Charlie Lee is the creator of LTC, genius, and he is most certainly not Russian.
