just hold on, cause i think this eth will have a great price in the end of this year.

I would leave 0.3-0.4 ETH and the remain 0.6-0.7 would buy some alts and participate in some best ICO. You will get some profits very soon. The march will be very profitable for the good coins.

i suggest you to hold your only 1 ethereum for 5 years.
Never use the private key around and never remember that you have 1 ethereum.
Come back 5 years later and calculate your profit

You should hold it! ETH is a must now atleast you holding a whole number not sats only. I promise you will never regret for holding this especially right now a lot of ICOs partnering with ETH.

if you have 1 ETH you should buy altcoin or participate in ICO or buy tokens that have a price of about $ 1-5 for daily trading or long-term trading and can make your ETH or your assets grow to much.

There are many options in the crypto market. when you log into the crypto money world you see that there are many altcoins. which you are surprised to invest in. Holding 1 ETH in your hand gives you money, but getting a altcoin adds more money.

etherium is a good cryptocurrency ..definitely no dought about it. but if you want more profit its better to invest it rather than just holding.i recommend you to invest on ICOs because it is the best way to get maximum for your investment. also i like to introduce good ico .its CVProof. i recommend this because of huge project concept which has high ground level value.project idea implemented on 2017 june and this is a long term project.CVproof allows companies to easily verify - and in a cost-effective way - whether an applicant holds the validated career credentials needed for the role. It is the first digital CV platform to guarantee full integrity around the credentials at each major career milestone.
so you can invest your ETH on this project which schedule to start public sale on 1st march.token price 0.12 usd per token

It depends what are your goals, do you have a strategy (short term or long term), but I would divide it into few good alts.

Holding ETH is recommended as I believe if Raiden network able to make ether lightning fast. The prices of ether will go to the moon. Best thing is to invest a part of your ETH in ICOs (Do research before investing).
I have participated in many ICOs and 99% of then are giving output better than the invested amount. You may also divide your ETH into few other tokens to reduce your risk.
