Free mining sites? Please keep off from those sites , there is nothing good to write about them. Mining takes a lot of resources, hardware, software, mining pool, electricity cost and maintenance . And someone said he is doing it for free. Watch out, I guess they just want traffic to their site.

LItecoins, Monero, Ethereum, Hempcoin and Waves are the best coins I will be holding throughout in 2018 to gain from the price increase. It has proven beyond reasonable doubt in 2017 that they are coins worthy of holding.

The past few days saw slow network on the Ethereum network due to the kittens and the price drop, but now is heading toward the moon. It means confidence in Ethereum is back?

It means the kittens that was causing slow network is over and people now believe is time to buy,hence the price up.

There are a lot of exchanges that you can purchase Ethereum direct with your usd using visa/credit card, or bank transfers. For example EXMO exchange and CEX.io

Initial Idea was to create an IOU to fund startup companies, but now the bad guys are in and taken people money away.

Ether is now trading around $600, do you think it will hit $700 by the end of this year.

EXMO exchange do accept visa and mastercard , but make sure you are verified.

Bitcoins fees and Ether gas, which takes more of your money when sending coins from your account.

Is safer always , just set your gas price higher and your transactons will move faster for your.

Litecoins is valuable and stable than Ethereum. For the past week, the slowness in the Ethereum network for the past week due to kittens trasactions make it less valuable now.

I agree with the fourth point. I involve in a campaing , where there spreadsheet wasn't updated for stake distribution, and finally we werent' answered in the telegram group. It later turns out it was scam.

Can you be specific the first thing that indicate to you an ICO might be a scam ?

There is nothing free lunch in the world. You need to work with your time. Even faucet, wont' give you free coins, it will ask you to perform a task by staying online or typing in a captcha. Why then not use the same time to involve in bounty campaing, it might pay off one day.

Virtual Cat, breed and sold them . I wonder what the world is turning to. What will one do with these cats, that is causing slow in our transactions.

No. Don't put all your egg in one basket. If you can do it 50% and BTC 50%, is fine.

The slow of Ethereum network is a test for Ether to prove is the next to bitcoins, with such abysmal performance, investors and traders will think twice of using Ethereum.

I don't think is possible in the immediate period for Ether to rise to that level. With regard to the kittens blocking the Ethereum network to slow it down. investors confidence in ETh will reduce.

Yes I check the website and told myself, if one has patient to see the roadmap of the ICO invested in to reach it final destination without selling the ICO , then we can be billionaires. but every one to dump at the market and move to the next one.

There isn't sure answer to your question on best coin to invest in. The best coins to invest in is the gainers on coinmarketcap for 24 hour range. No coin is sure to be best for ever.
