Depends on how much money you have.
If you have a lot invest in all 3..
If not then invest in Altcoin. ETH or something else.

It's kinda hard to say now.
Prices are going down all the time.
But if Nuls price goes down to 1.80$ you should invest that would be easy 2x.

For me Ripple is better than Litecoin.
Not saying that Litecoin is bad or anything but Ripple is a bit better.
I would invest in Ripple.

It depends if it goes like this then the price most likely is to be around 800$.
Prices are falling a lot every 3/4 days.
If it goes good then ETH will rise.
ETH is a good coin all tokens are build under ETH platforms.

Both are good but Medium bans accounts that write about bounties.
You can use minds.com that blog website doesn't ban about it.
For steemit I don't know if it bans people.

Maybe, don't know for sure.
But even if it gets hacked I don't think they can access your wallet without your private key.

That is not true lol.
A lot of altcoins have a good future and they are not scam.
ETH is a altcoin too and it will be #1/

It depends on the amount.
It's better to hold but if you want you can sell if you need money or etc/

There are many exchanges you can use.
Like HitBTC , Binance and Bittrex. Binance and Bittrex are very good exchanges and popular/

Both are good.
Both price is low.
But I would choose Ripple.
Or if you can add a bit more money buy both.

You need to read the rules.
All campaigns accept posts in cryptocurrencies.
So you are posting in the right place.

ETH is like always good for buying.
You can buy ETH now. ,it's 690$ but that will go UP for sure.
Invest in long term.

Both good coins.
If you have enough money invest in both. ETH and LTC.
If not then go for ETH

Everything can happen.
I would recommend to hold your investment.
Maybe it will the coins will rise again noone knows.
If I was in your place I would hold.

Do both.
Hold ETH but other alt coins.
There is no reason why you can't hold ETH and other coins.
Do that.. Sell some of the ETH and buy other.

What's the lesson you learned?
HOLD YOUR COINS.
Long term holding is the best.
Yea if you see the coin rise a lot in very short time you can sell but if it doesn't then dont/

When Ethereum was under 400$ was the best time to buy.
Now you would have doubled your money. In 1 month.
Almost every coin was good to buy when the big crash happen.

1000$ a month is a good amount of money.
Some people like me can't participate in translation campaign that's why we focus more on signature , content creation and other campaigns.

To find the perfect ICO you need to do research,
First write on google ICOs there are a lot of links with ICO lists.
Then choose an ICO check their whitepaper,sales, group and etc.
And decide if you are interested in investing.
