While bitcoin will not cost $ 100,000, do not even think about investing or not. But it is better to wait for correction if possible.

it depends on ico's project support with the ico that is really down to the price and even for years to hold the coin hold that the price will not increase so it's best to read their project so as not to lose your investment and there are coin is also as high as the price at first and you hold only a few months to increase the price so hold only the beautiful coin hold

What is not seen is the rise in the price of bitcoin. And if it does not grow then the other violas do not move. Until stable growth of investment is risky

This is possible, but not on top coins, since they already have huge capitalization at the moment. But there is a possibility that the whole year the prices will fluctuate around current levels and we will not see any growth or falling.

I'm talking about the top coins. I'm expecting $ 70,000 for bitcoin by the end of the year.

Now is a great time for investments, based on historical facts. Always when the market is down, time for investing. Because the investment can be minimal, and the moment when the market goes up not far off. In accordance with this, if there are available funds, you can and should invest.

There is no good moment and a bad one. In all markets, we must always enter gradually to reduce volatility. if you also think that in the long run you go up then you have to invest slowly

As I always  say  every price movement of bitcoin  or
 altcoins will become  an opportunity  low price  will be an opportunity to to invest while high price will be an opportunity to sell. But  if everyone has  that  reaction  to buy and sell  immediately after price movement and  only few will hold  we expect  bitcoin to be more  volatile.

Certainly you should invest. Currently is good time for buying tokens and taking a part in ICOs. Crypto-market is constantly evolving. Don't miss the chance to become richer.
Take a look at this new project  -  Velix.ID representing a multi-level blockchain for identifying and storing your personal data. The idea of the project is to create a single decentralized database which organizations and various institutions could address to.  Great idea! 
 I'm sure about the perfect future of Velix.ID.
