i think it's moment to buy coins to invest because the market price is going down, but it still risk to invest for me

Now partially buy the ether because he's been dropping. I'd definitely buy. And then he'd buy more if he fell harder. then it some good news will restore its position and you'll be in not bad profit

It is impossible to foresee the future. But it is quite possible to make a portfolio competently. In general, the crypt will grow, which means that if you make a diversified portfolio, the profit will be significant.

if you have 100$ for investing, put 50 in it now, and wait for next dump.

The market looks stable now. There won't be a huge dip anymore(like it happened in december). Though with people investing more and more in bitcoin will result in a significant increase in it. So you can definitely invest in bitcoin right now.
Altcoins may increase if the respective organizations tie up with other organizations so it's market is not the least predictable.

It all depends on you. because investing is very risky. But investing now, this is a good time to invest with bitcoin or altcoin even though it may be a little late. the price is still very arguably low, buy as many coins and hold until the price back to normal or rise.

It is a topic that discusses investing or waiting when the market goes down. If you want to promote the ICO project to everyone you can post a question to introduce it to everyone and discuss it. And no matter what your plan is promoting scam or not.

Now is a good time to invest coz the price is still low as bitcoin is just recovering hes price. After a few months if bitcoin is recover the price mostly all altcoins also goes up.

To the highs is still far away, then now is the time to invest. I think that if you choose the most fallen (relatively to peaks) coins and evenly invest in them, then the revenue will be higher than the market index.
