We worked with ModernToken, the pricing was good and the result they provided also good

This depends on the project itself. If I see a lot of potential I am willing to invest more, but for projects that only have a certain level of potential, and dont look that promising to me, I rather go in with a little money, just in case it takes off. So that I dont loose out if it does. In most cases I go in with around $250 - $500. But this strategy also failed in more cases then it did work out, most of these ICO's I invested in are now below ICO price and I would have had a lot more gains if I just stayed in BTC. But thats the risk.

I think market will start growing back and stabilizes by march

A lot of ICO in current market in which you can except a good return. Some of them are here and you can get full list on CoinKhoj.com:

1. Regen Coin (REGEN) : Regen coin is a lending platform, so investment is riskful but profit is more, invest on your own risk.
2. Game machine (GMIT) : Game machine is a good project and it a platform like ethereum for gaming industries where game developer will create their own ico and sale to investors. When game is published, investors can sale their ico/token to gamers and gamers will pay by mining coins instead of paying fiat currency. This ecosystem is realy remarkable.
3. Tokia (TOK): Tokia is a wallet and exchange service provider for all crypto currency, it have greater hype in current market.
4. ModulTrade.io (MTRc) : It's a trading platform for small companies all over the world. The idea is to make global goods trading easier for small entities
5. Goal Bonanza(GOAL) : Goal bonanza is sports betting ICO. Mainly for football betting. We all know how football betting have large potential of income in their business. Goal bonanza decentralizing this opportunity to take part in the gambling business.
6. Crypterium (CRPT) : Crypterium is the next online bank for crypto currency. It will connect 42 million store by integrating it’s payment gateway. It will integrate it’s payment system with paypal, paytm like companies. It will be next big thing and ROI potential is also more.
7. Indahash (IDH): Indahash is group of influencers. Influencers are like motivator, which are promoting a business or product or service of a business. A lot of sites on internet which recommend to use a product from amazon, flipkart or any other’s product, they review that product and represent that product in article or video and motivate user to use that. It is also have it’s potential return.
8. Martcoin (MART) : Martcoin is also another betting business startup launched ICO. Martcoin aims to provide 200+ betting service in it’s platfrom.

That's very common behavior when you only start trading. It's an experience everyone of us have. So hold on and continue. You'll earn way more in future and this will be a story to laugh about

I'll advice bitcoin and ethereum for holding and ripple and neo for trading.

I think that the main problem of ICOs is that the expectations are enormous — too optimistic to be honest. The world won’t be overthrown by blockchain in a year or two. But for me for now modultrade is quite a good choice.

You should make a very good research about team and project itself before considering investing in it. But there is also possibility of taking part in bounties, that can bring you tokens of projects you're interested in, without putting money on the table

I've just invested in ModulTrade. It’s a smart-contract blockchain based trade ecosystem. It brings together a comprehensive range of services for the full B2B trade cycle. It’s really great and ICO is already going.

I'm already watching your project during some time, already invested. And I want to tell you that the job you're doing here is really gonna change something. The idea of facilitation of global goods trading for small entities is brilliant! If for example I want to buy a giant wooden slab from a small shop in Bali and I want to do it being in US, there's so many additional costs to proceed payment that that slab turnes golden even if the initial price was resonable. I hope your project will help in such situation.

Bitcoin is not anonymous, but, rather, pseudo-anonymous. By now, most Bitcoin veterans know this. It’s less obvious to many, however, why Bitcoin is not really anonymous by default, and what can be done to de-anonymize Bitcoin users – and what Bitcoin users can do to reclaim their privacy.

Try reddit and steemit

You can have a look at bitcoinwiki.org for that

I agree, bitcoinwiki is a very good resource to start from

For good crypto exchanges I will suggest Binance now because in binance we can register easily and the service is so fast and also binance has low fees for trading and withdraw. Other good exchanges is Bittrex, Poloniex, Kucoin and Freewallet. But in bittrex and poloniex you have to verify your account first to deposite and withdraw and it takes much time and I heard that Bittrex is not accepting new account now.

i think coinbase because backed by trusted investors and used by millions of customers globally, Coinbase is one of the most popular and well-known brokers and trading platforms in the world. The Coinbase platform makes it easy to securely buy, use, store and trade digital currency. Users can purchase bitcoins, Ether and now Litecoin from Coinbase through a digital wallet available on Android & iPhone or through trading with other users on the company’s Global Digital Asset Exchange (GDAX) subsidiary. GDAX currently operates in the US, Europe, UK, Canada, Australia, and Singapore. GDAX does not currently charge any transfer fees for moving funds between your Coinbase account and GDAX account. For now, the selection of tradable currencies will, however, depend on the country you live in. And of course I should mention FreeWallet. It is very convenient to use, rather fast and nothing have ever been stuck there, the longest transaction I had was 3.5 hours, but normal for ICO crypto, which I put out into BTC, most likely. And in freewallet you can sent BTC without commissions, although usually it is around $15, so this is a very nice bonus.

For example Joseph Stiglitz said on Bloomberg TV that cryptocurrencies like Bitcoin should be banned. His commentary is based on analysis saying that the market for Bitcoin is driven mostly by its potential to circumvent government agencies. And also the Bitcoin market will ‘go up, and then come down,’ leaving many investors injured, and therefore it should be banned, adding that it doesn’t serve any ‘socially useful function.’

Here's great web page where all news about countries banning BTC are listed http://bitcoinbans.com/

I don't think it's good time to invest in ethereum, because its price didn't fall much. I would advice to look at BTC prices. As for altcoins I would say, XRP, XLM, TRX and LTC are good deal now. Now all the coins have fallen after New Year that you would get a lot of coins for your money. In a few weeks they will rise again.

Probably Ethereum has the potential to beat bitcoin in market cap, but that not change anything. Never forget bitcoin is a good technology with a good store of value, and have a strong community behind his back.
Ethereum might not ever reach Bitcoin’s individual coin price simply because there are a lot more Ethers out there (and no set cap) vs BTCs but the overall market cap will be exceeded relativity soon. They are only $8 billion apart and I anticipate that Ethereum’s market cap will be above Bitcoins.

I can advice you to check https://en.bitcoinwiki.org/wiki/Main_Page page, it's a perfect resource for beginners to start gaining knowledge about crypto.
