"public" key is public. You can share it. "private" key is private. You should be very careful, there are many fraud webpages on the internet, which may has a very good interface. Do not share private at all.
When you open waveswallet.io, you can see the key on top of the page, that public key can be used for trades.

Green, todays, is the name of a color we miss seeing. Spring is coming, we will see green everywhere, but we want to see green in our portfolio as well. Green, is a nice color.

VEN and SYS have a good future. I like the project, i like the team, i like how they proceed and follow their roadmaps.

ICX is one of my favourites, I invested a considerable portion of my money to it. I suggest, it has a good team and good future.

The increase is crazy, but wait for decrease in such cases, it always happens.

Waves has a good team, but dex platform needs some improvements and the volume is not that high. If the volume increases, Waves would have a good future. I support holding it.

Think it as that you are assigning a value for the project, the price of it is determined by the team but note that they want to reach hard cap. If the price is so high, they cannot reach.

For mining purposes, LTC is more profitable. The community of it works very well. But I always suggest both of them.

If you will hold your money more than 6-7 months, it is time to invest your money. If not, wait for a stable marketcap condition.

I was joining like everyday 3 months before but I quited. It is not waste of time, but it does not worth I think.

I wait for the WAVES for a long time. It is really good and undervalued. However ETH has a stabil increase in its price. Any of the choice is optimal, divide 50/50.

ICX, VEN and AION are my favourite three coins. I believe they will be in very good positions in the cryptocoin-world soon.

Yeah, I would invest more money in this scenario. I believe that everywhere will be green in the next month (and wish that of course)

Good news. It is time for a green table for the cryptoworld. Looking forward to see it.

OMG.. Yes, scams are everywhere. You can confront with such a picture.

Both are good, I am happy with my Ledger. I can suggest it.

Definitely, ICX is a very good project and in 2018 there will be a good increase of its value.

Mining has many aspects needing for consideration, simply investing BTC for the long term is more profitable.

You should always stay away from them. It might seem adventageous but it is not, I can ensure you, with a couple of year experience in this cryptoworld.

The important points are already stated, but consider yourself as you are selling your house and investing all your money to a project. How much research would you need? Make your research as this, and you will select a good ICO.
