I think it is maybe because the Bit-tube addon should analyze the website you are viewing to be able to remove the code to not display advertisements? It can be considered as a kind of virus.
An extension can also read anything you type on a webpage.

That's why you should be careful when using an extension on your browsers. It is better to have another internet browser without any extension if you want to do private things on the internet to stay safe.
And still have hope that the browser is safe and don't do malicious things.

I think the bull market has already started. Yes, yesterday we have seen a big decline of Bitcoin and altcoins after the trial for Bitcoin to reach more than $9000. But i think the coins need a correction. A coin can't just increase without any correction, else it will fall like a stone.

I don't see XRP at $10. Except if 1 Bitcoin is worth one day more than 60k USD. But i don't think it will happen so fast. A lot of people still have doubts about the value of Bitcoin. It will need a lot of years and governments and banks have to accept it.
XRP highest price was near $3.50. Maybe it will be worth $7 if Bitcoin value can reach $40000.
But don't forget that a lot of XRP are locked. So it should be worth near 2 times less if Ripple's company release all their XRP.

Dogecoin is not a bad investment. It needs a lot of time to see an improve of its price. But when it will happen, it is going to be very fast and high as usual. You need to be patient. Don't put all your bags on one egg.

I also think that we will reach 10k for this summer and i don't think it will fall under 9k if BTC reach 10k. The bull market is still not finished.

Any coins in the top 100 except stable coins are good to buy for 2019. Some coins not in the top 100 can give you better profits, but they are more risky as they are lesser known.

There was a rumor/news about chinese people who did pump the coin because of a fake news that fakesatochi did withdraw 50000 BTC from satochi wallet to an exchange. And that CZ was going to apology to Craig Wright because he is Satochi and reinstitute the trade of BSV. I don't know why it is still pumping as people should have heard that it was fake news. Good for fakesatochi.

The need of money and greed won't stop hackers and scammers. Sometimes it could be someone in the exchange who stole the cryptocurrencies. Cryptocurrencies wallets are just numbers and that make them difficult to tract. And every exchanges and people should be aware of the wallets who got hacked. And there is maybe no mecanism to stop them from transfering the stolen coins to other wallets and exchanges.
If you don't want to trade for a certain time, it is better to keep your cryptos in your own wallets.

It is the first time i am learning that there are telegram bots wallets. I won't put any money into them as i prefer to use the official wallets. The telegram bots can disappear without leaving any traces.

I still believe that the bull market is going to continue. There is certainly still some people who have doubts about it. But i think more people now  believe that the bull run is going to continue.

Try to install the blockhain wallet app on your phone. I had some troubles with my browsers on my pc too. I think i did succeed with the mobile wallet.

The best time to invest was in January. But there is still chance to see more increase for BTC and altcoins. But it is better to invest only what you can afford to lose.

The roller coaster could repeat i think. Altcoins now are very cheap compare to BTC, they might come back later. For the moment, they are stable compare to BTC. I hope this will happen.

It will help Facebook collect more datas about what you buy/sell. And who has the more money. After collecting the identities and ideas of peoples, they now want to collect the finance of their users.

Yobit could be a replacement of Cryptopia. Both were proposing a lot of altcoins to trade. Tradesatoshi has also a lot of coins, but Yobit has more users and the volume of trading i think is bigger. But there were problems on Yobit if you wanted to buy coins and send it at your wallet, as their wallet was not synchronized with the blockchain or not updated.

Surely someone did pump the coin. It can also be the work of a pump & dump team. Any coin can be manipulated if the peoples pumping it have enough ressources to do it. Only the exchanges really know who is behind a pump.

It is only for marketing purpose. How could you tell people that this coin exist? Without doing airdrop, nobody is gonna be interested in their coin. The amount of coins given is too small, but it can make people curious about it. And maybe new investors are going to buy it.

It can be true that it was a pump scheme for Binance coin. But nobody really know if it is true or not. But i won't be surprised if it is true. But the dump has still not arrived. We don't really know what is the price when the dumping will start.

It is important to look at the price, as sometimes you buy an altcoin at a too high price. Except if you accept to lose money, price is the first thing to look at. A coin development is also important, but sometimes the coin just stay on the sideway as too few people know it.

I prefer to trade cryptos than doing shopping with cryptos. It is great that it is possible to do it. But as the volatility of cryptocurrencies is very high, it is not a very good idea i think. Playing casinos is still a possibility, as the goal is to earn more money.
