I belive that the coin Pura has nothing to do with avalon life, it must be a coincidence, you can mine pura but I have no idea how, the code and wallet for pura can be found here
https://github.com/PURAcoin/PURA
Maybe this will help you

Good strategy. A better one would be to sell enough to cash out of your original investment (in your example looks like about 60% at time you sold) and then let the rest ride as at that point it is essentially free money. With these pump/dump coins I think getting your original investment back first is a priority and holding for future gains the secondary goal. With better established coins such as BTC, ETH, LTC and the like you can have more confidence the coin will last long enough to get out at some future point, but with some of these coins you may end up bag-holding for eternity.

pura coin is good volume transaction, although only accepted trade in coinexchange
why not added to bittrex exchanger

You have to do nothing more, and no, dev doesn't have to do this manually, therefore exists a script

Can anyone remember any coins that stake even when wallet is closed, like nem harvesting? Also would be nice to hear about stake coins that you can have on your phone, I know of energy coin. Any more?

There are others who can answer your question more directly, but here is a quick overview of Zen

Elements of ZenCash that are different and unique from most other cryptocurrencies. Others have them, but not in this combination:

Private Transactions – Advanced crypto technology (zk-SNARKs) used for private transactions, communication, and publishing. zk-SNARKS enable transactions of ZenCash without revealing the sender, receiver, or amount onto the blockchain. ZenCash also has traditional transparent transactions available for use, where the sender, recipient, and amount are recorded and available on the blockchain (just like Bitcoin).

Encrypted and Resilient Network Transport – Create and maintain a stable and secure network to operate Zen with Secure Nodes, paid for when a Zen block is mined. There will be thousands of Secure Nodes all over the world for ZenCash wallets to connect to, and network communication from wallets to nodes will be fully encrypted.

Funding for Viability and Growth – Ongoing funding of the treasury to pay for development, marketing, and partnerships. This is important to adding features, keeping applications current, and having a team who looks after and cares about the needs of the ZenCash users.

Inclusive Governance – Governance with participation by all people involved in making ZenCash work – Zen Blockchain Foundation members, developers, owners of ZenCash, secure node operators, mining pool operators, exchanges. All people involved with ZEN are stakeholders, and owners of ZEN are encouraged to participate in governance to influence the direction of ZenCash.

Definitely XSPEC. And here is why:

XSPEC is a privacy focused coin with unparalleled features. No other coin has the combination of:

• TOR integration
• Implemented fully with hidden services
• OBFS4
• Zero-Knowledge Proof
• Stealth Addresses

Now, with some governments trying to control crypto-currencies and limit privacy, coins with high anonymity will become even more important in the future. BTC, ETH, etc. are far from truly anonymous. But even coins, such as Monero, Dash, Pivx, Verge, are technically inferior and can, if not be "broken", then at least be blocked. Countries such as China and Iran, block Tor, and thus Monero etc. cannot be used securely in those countries. XSPEC does not have those limitations, and is thus the only truly untraceable and globally accessible coin.

Furthermore, using PoS v3 instead of PoW rewards ownership and with the planned Android wallet, it will not only appeal to all truly privacy conscious users, but also to people who did not have access to such a coin before.

As the devs have focused on developing a superior coin, but have not yet made much of a marketing effort, the coin is still vastly undervalued, despite being already featured as the 4th best performing ICO in history (in terms of % gain)

It looks like ARK is about to pump again I might buy some now.

Zencash is still new, it's the best time to get in early. It's still under the radar. One of the main advantages is the secure nodes, which makes the whole system decentralized. I don't know any other major privacy coin doing this. Zen will be one of the top anon coins in the coming months. There is still a lot of money to be put into development, the team is strong.

Antcoins/GAS has been pumping hard:
https://www.binance.com/trade.html?symbol=GAS_BTC

I've been buying Antcoins on 19800 for less than $2,-, they are trading for almost $15 now. I regret I sold most at $9-$12  I always knew GAS would have potential, but this is beyond expectations. When it continues like this we will see the Flippening, I think within 7 days. Any thoughts on this?

ps. Read my post history on ANC/GAS, I made the call a while ago.

Good for you and always remember don't sell at a loss. ICN will soon begin to take off.

No, you dont have the private key

If you have an account, dont forget to activate Google 2FA

Yes, iconomi.com and iconomi.net is the official site

Yes you can hold your coins on the platform BUT you will need to get verified if ever you want to withdraw them from Iconomi platform.

Other option is you can buy a hardware wallet and store your ICN tokens there.

I am personally storing my ICN on the platform, waiting for the debit card to be released to be able to do a conclusion incase i request a card
