I think it's better to buy from ico, because we will get a bonus and maybe from bonus sales we can return the first capital.

now the stage of buying, currently the market is stable at the price below I suggest buy or restock alcoin bitcoin plug the price down so if the possibility of a buy, if the possibility of selling and restock back because seen from the current state of the market is not too large volume on each altcoin or bitcoin so I recommend playing short-term trading. if you want to play long-term buyback keep down and hold buy ETH I'm sure that its future it will rise back to the price of $ 700- $ 1000 USD if the cryptocurrency market again improved on the volume of each market

I would say the best time to buy is from an exchange.  Not all projects have ICO's and if they did, buying during the ICO doesn't guarantee it will be the cheapest price.  Many times I have seen prices on the exchanges being cheaper than the ICO price. 

This cannot give correct conclusions because the actual situation is always changing. Remember that it is alive, not fixed. So there is only one way, when it falls sharply, it is bought, not sold.

When the bitcoin is rising in value.  People tend to dump Altcoin when bitcoin is  rising. And if you are targeting lower price and you want to get more deal with maximum offer,  wait for when bitcoin price is rising fast and buy to your satisfaction.

Right now is the best time to buy, altcoin prices just started to rise slightly and they are expected to continue to increase until the end of 2018. So buy and hold them now hours are still up.

If you want make investment in alternative coins are like ethereum, ripple, EOS, litecoin, bitcoin cash and other alternative coins, today is good time for buy them and hold for couples months later, usually the of alternative coins goes up until the end of year. But if you want make investment in ICOs projects, the best time to investing into them are on ICO stage and don't forget to do analysis about the ICO before making investment.

The recent bear market was an amazing opportunity to hoard a bucket load of coins or tokens that you were interested in and that time has already passed. The entire crypto market has already started rallying in a slow and steady manner and I doubt that this rally will stop anytime soon unless there is some crazy bad news which seems unlikely. I purchased some coins that I was interested in like Einstenium etc and am happy to see my entire portfolio in green. I believe that this is still a good time to purchase altcoins that you are interested in since majority of the coins are still undervalued.

ICO stage It is a very good time, usually at that time the price is very low, especially good projects start a large increase, mainly ico when there are too many restrictions, many times can not be bought, and after the price on the exchange Already high.

If the project is good then it will be on ICO stage, I knew some good coins that actually only developed by small team of small project, this coin price is grows little by little although this coin price also fall when there are some problem in it's project. For example you cam check XCPO, the project is good but it's have many obstacles. After it listed in first exchanges is also good time because usually bounty hunters are dump their coins so its co8n will be undervalued. The most important thing is the project.
