These sell regularly on Ebay. They are usually sold funded and well over the value of the bitcoin in them. Be very careful if you accept paypal payment due to cashbacks.

Do not donate if asked for by airdrop. Genuine airdrops do not require donations. Do not give private key to airdrop.

There are genuine airdrops. My most profitable was POStoken. I do not send ether to receive airdrops as I do not accept that such requests are genuine airdrops.

I think demand for ethereum is increasing due to ERC-20 tokens.These are being traded but need ether for the transfer hence demand increases.

I convert my holding into litecoin when using exchanges as it is both cheaper and faster. Those high bitcoin fees will kill trading in small amounts.

You can really only make money mining bitcoin if you have a cheap source of electricity. Ask where they are mining. Definitely not in UK.

Etherdelta is special because it lists more ERC020 tokens than any other exchange so has an almost monopoly in that area.

Is it safe to log into etherdelta using myethetwallet private keys? Surely this gives access to your etherwallet by etherdelta?

I use bitfinex. Loans are given for two days and rate changes throughout the day.

Mine is in an exchange. I am going to hold hopening for a price increase.

Nice clear easy to use site. Only problem would be updating by not only adding new airdrops but delisting out of date drops. Hope you do well.

Basic questions. Nothing intrusive. Is this a university project? Best of luck in your project.

Why not buy back half just now on a small dip and keep the rest for a larger dip? If it goes up you gain on what you bought while if it drops it lets you buy at a good price until next price rise comes along.

Bitcoin is less than $100 short of $8000 on bitfinex at the moment. It was over $10000 on Zimbabwe site yesterday. Bitcoin will hit $10000 but nobody knows the timescale.

Everyone says buy low and sell high but very few can sell at the peak and buy at the trough. Do not sell after a large drop as you will probably end up having to buy back at a higher price.

Nobody should be giving their private key to any site. Any airdrop that asks for a donation before they can receive tokens should be avoided as that is not an airdrop. Many airdrops supply a low amount of tokens so the holding value is less than the exchange fee.

I have read that etherdelta require your private key. Surely this is not your Mew private key?

Obviously social sites like twitter and facebook have links. Telegraph have a good number of groups. A google search should give you enough with the previous link suggestions. Be careful that you are obtaining facts and not holders of coins trying to pump their coin.
 

It depends what you want to be involved in. If you want to buy the main coins eg bitcoin,litecoin and ether then the big exchanges are ok but if you want ether tokens then there is really only etherdelta.

There are a few problems with arbitrage. Although you may find a good price difference between exchangers there will be a time difference for the transaction. Price could change in that time. Withdrawal fees from exchanges can eat into profit.
