From where are you?
It doesn't matter whether is bitcoin seen as currency in your country or not, after you exchange it to fiat and cashout to bank you are obligated to pay tax according to your local law.
It is like selling fruits on internet, if you sell apple for money you have to pay tax.

Wait for price to go up and then sell tokens. Or sell as soon as possible. Do what you want, after all you are here to make some profit. Holding tokens is riskier but if you "hit" good bounty you might earn big money, but project can fail too and you will become bagholder. Always thing twice before you make any move.

I am ethereum user because I can't send erc20 tokens without it. If I could send them without paying fee with ethereum I would have never bought eth. My final goal is to have bitcoins and not ethereum, and there is reason why users have to choose more than one wallet - decentralized exchanges and phishing scams. It is not smart to enter private key with all funds in decentralized exchange(remember ED hack).
With bitcoin is much easier, you basically need one wallet with one address and that's it.

Tidex. Anonymous exchange without daily withdrawal limit. I used it several times in last 10 days, only time they didn't allow me to withdraw funds was when I changed password - and I wasn't allowed to withdraw funds for 24 hours, after that and before that everything went smooth. I don't have a single thing to complain about them.

You are suggesting NXT because you have bought it at very high price and now you can't sell it without loosing some money. I don't see bright future for NXT and I don't think investing in nxt is good decision.
Get used to it, people are always asking financial advises in wrong place. Most people will suggest coin which they own because they want to sell it at higher price.

I hope not. I would like to see slow but stable grow rather than fast and unstable. Look what happened last time, btc value has mysteriously increased its value to $20K and then it crashed to 6K. I think we are lucky that crash wasn't deeper.
My prediction for this month is 1btc = $12K.

What is there to explain? It is donation, like every other donation.
For someone who has 10000 ether it is nothing to donate 7-8 ethereum, but for someone who doesn't have even 1 eth it looks like lots of money.

Whatever you choose, as long as you are buying on dip.
OP said that he has 1000 euro to invest and you say that it depends on his capital, at least read topic before you post anything. Why do you think ETC is perfect choice?

I don't think there is a way. It is like you were ridding a bike and your wallet fall out of your pocket.
Good for you it is very small amount of money, forget about it and next time write your wallet ID and private keys somewhere.

That is perfect example of how people should trade.
Great job buddy, can you share with rest of us mortals how much profit did you made? Of course, if this is not top secret classified information 
Btw I think your portfolio will increase much more.

If there won't be any changes on MEW I don't see why should I stop using it.
It is fine wallet and it suits my needs.
OP is there any particular reason why we should change wallet or you are only gathering information?

Yes, train is gone and you have missed it. You should wait for next train. That is how trains works, they are always circulating.
Which means:
It is never too late to join crypto. Jump in and enjoy the ride 

What are you talking about? I've traded some coins just recently and everything was just fine.
They should be in etherdelta wallet. You need to withdraw them to your wallet. Can you provide us more info on this issue?

No, for every bounty campaign there is public spreadsheet where you can check your stats and track your stakes. Everything is in there, sometimes campaign managers are counting posts manual and sometimes they use bots and finally they write all numbers in that spreadsheet. Campaigns should be transparent and public so as all other campaigns, yours have spreadsheet too.

I don't agree, 500$ is very small amount and with that OP should look for undervalued low cap altcoins with active team and solid future.
Stellar is good, it has bright future and active team but I am not so sure that it will grow big. OP should look for coins which are under half dollar.

Buy and use it.

Holding won't do much for crypto.

Bitcoin has to circulate and than we will see natural grow. If everyone is holding and no one is using it what's the point of it?

Market will recover in few months, but it will start recovering somewhere around 20. February.
It is Chinese new year, they need money so they've sold all crypto, as usual they do every year and every year in January we have crash. Look at the charts from last several years and you will see what I am talking about. Every January the same thing.

No, panic buying is something different.
Panic buying is expression for those who are buying when it is too late to buy, for example coin A is worth 500 satoshi and someone pump it to 5000 satoshi. Now, because of FOMO, people are panic buying that coin, pumping price more while person who pumped it to 5000 sat is waiting for a little bit and sell his bag.
Which leads to crash. Which leads to panic sell.

In your case, if you buy now it is not panic buying, it is smart call.

No. Buy. chart scream "weak hands".
Why do you want to sell it can't you just use it and buy stuff over internet in stores which are accepting bitcoin? Be useful to community, start using bitcoin as you should and if we all start using bitcoin as we should price won't crash, don't look only at profit because bitcoin wasn't created for that reason only.

Can you link us to place where you have read this?
Because most news are fake and this is something I like to call fud and internet is full of fake news.
