You can't focus on 10 coins correctly, even beeing a full time trader. You'll miss calls or information, or conferences/roadmaps.
You should take 2 or 3 altcoins that you believe in and stay focus on them.

I don't believe 10 altcoins will be huge in the future. In the traditionnal world, there are many business that have been started out there and there are less than 10 that have really worked well and continue to work well for years (google amazon apple... etc).
And don't think among the current one, 10 of them will be running again in some years...

For better for the Bitcoin whales
For the worse, for the altcoin holders.

Everybody knows that the development modification are so tiny and the only thing that it will do, is makes the richest richer, and destroying the altcoin market...

Myetherwallet is like a mailbox.
If somebody wants to send you a mail, he needs your adress, which is public.
But if he wants to know what is in your mailbox, he need to have your key, which is private thing.

Myetherwallet is the same.
You create it with a password, and you'll have a private key (your mail's key).
There is an adress attached to your "account", which is your like a public adresss for the mail.

Then you send your ETH to other public adresses.

If you don't know nothing about coins, I suggest you to only choose the "hold" strategy. Choose a big coin, and keep it many years.
Don't try to daytrade with altcoins if you don't know what you are doing. Just an advice before you loose all your money on a shitcoin.

Choose and keep BTC for the beggining, then learn, do some research, and try altcoins when you know what you are doing.

Everytime a coin is down, somebody is gonna make a post about it ?

Cryptocurrency is volatile, you can't expect having always pump. Just give time to the altcoin you invest in, or daytrade, but please stop asking why it's down everytime there is a down...

Mew is the wallet used by a vast majority of ethereum user.
Check the official ethereum website if you want all the information, don't ask other people to search for you, or sometimes you will loose all your money because somebody told you to invest in something stupid...

By the way my ether wallet is not a website with storage, it's an interface between the blockchain and your computer.

If you have a lot of money involved, you shouldn't ask other people how to take care about your money...
I suggest you to check the projects that you love and invest in what you believe. You'll be very frustrated if you loose all your money on an scam ICO that other people told you it would be amazing...

If a businessman come at your door and tell you to buy his new woodstick because it's the best, would you buy it ?

ICO are not regulated.
If in your mind, paying somebody without having a service or a good in exchange, is not a scam... What is it ?

If the developpers want, they can leave with your money and nobody will say anything because there are no laws behind it.

If somebody calls you and tell you, please donate 20 000 dollars for the XXXXXX fundation, we are going to build this and that, it will be great !!
Would you give him money like that ?

Airdrop doesn't compete with ICO, because generally airdrops are the step before an ICO to make the coin become popular.

Airdrop is not a bad thing for user if you don't have to download anything. It's free money, but generally very low value at start.
Some of them might become famous, but as Vitalik said, 95% of the altcoin will fail at the end, so imagine for the airdrop of unkown coins...

Bad news for people looking for rare coins...
I'll have to look for odd and dangerous exchanges again, from china or other far away countries

I will finish having  so many accounts everywhere that I'll lost myself xD

You can go to http://coinmarketcap.com/ and check where is your token, you can then search on this token page, what exchange it is on, and other stuff like social network of the project, website, and many other technical things and values.

Generally, shitty coins start appearing on etherdelta, an slow paltform where you can buy and sell odd coins. Be carefull with the gas fee, if you forget to set it correctly.

Enjoy

Sorry for you, but you didn't receive any ETH in your wallet
As previous posters told you, when you check the transactions, it's XNN tokens, that come from an airdrop.

Check the value on the internet, but spoiler alert, it's not worth 280 dollars each

Yes I sold them all...

As there will be apparently more and more fork for BTC, there will be more and more useless and unused forked coins, that will obviously loose values with time (because nobody will mine it and use it while there is the real and main BTC coin that everybody use)

You can wait a random pump out of nowhere, but I suggest you to sell every BTC that will be forked in the 3 or 4 first days of their existance... Except if they have a real usefullness, like monera (which was a fork of BTC).

Have a nice day

Litecoin has pumped some months ago... You can't expect to have pump every weeks, and if a coin pump regularly, it's always but a proof of stability.
Litecoin value is stable, and will probably continue to raise step by step. There is a difference between underperforming, and dumping... Litecoin is well at this moment, but it's not the coin that you need if you want to have a 300% return of investment...

Generally, unkown coins are sellable on etherdelta.

If you want to know where can be sold your coin, you can go on https://coinmarketcap.com/ , there is all the information that you need. Particularly, the exchanges where everycoin are sellable.
You can also check the social network of this one, the marketcap, their twitter, their website... etc

Be carefull with etherdelta, it's generally a really slow exchange, with some high rates if you don't manage your gas fees correctly.

The best ICO I invested in was MCO (Monaco).
It was a cheaty project nearly a SCAM, and I succedded in sending my coins some months ago at 500% of their initial value.

I don't think I'll invest in ICO anymore, because it's pure luck and speculation. Good projects can make you loose so much, and bad ones too. And sometimes it's the contrary, for no reasons...

I advice you to stay away from ICO

Remember that a wallet is just an interface

It just shows what is in the blockchain. If you can't access your wallet, your assets are still in the blockchain, it's just that the interfaces have difficulties to display it.
Technicaly speaking you still can do some transfers by other ways.

Every coin has its own wallet.
You can't have NEO on myetherwallet for example.

So if you own ETH coins, you can use myetherwallet. it's an interface that communicates with the blockchain.
It doesn't store anything, there is just a link between you (your computer) and the blockchain.

For Bitcoin, you can use Electrum... etc
There are plenty of them, the code is generally the same, it's just the interface that is different. I suggest you to make some research on your own, if you don't wan't to throw away your money... The best thing is to use the recommended wallet of the coin that you own.

Just be carefull to click to the good links and don't use fishing wallet with wrong url that keep your passwords

Full of expectation ? LOL ... Make me laugh xD

Just 30s of google research...


Bitcoin Gold does not currently have:
    -Fully formed consensus code
    -Implemented replay protection
    -Adequate code for testing and auditing
    -Publicly known code developers

Bitcoin Gold codebase also contains a private premine of 8,000 blocks (100,000 BTG). Please be aware that if a market does open there is a possibility of the developers selling their premined BTG on the open market.

Bitcoin is already not really a technoligically advanced coin, so I don't know what to say about a fork of this coin, that nobody wanted, and is pure speculation out of nowhere, without project and ready to die...
Please... Full of expectation

Etherium is not a decentralized crypto currency because Etherium doesn't even exist...

There is another coin that you should maybe focus on, and that has been very famous for some months, and it's called Ethereum
