As I already said earlier while the Bitcoin was traded between $5000-$5600 that the market should be in a stable mood so that then it further decide it's direction itself. In this level the Bitcoin price stable for some long time and then break the level at below and decline below $4000. If it breaks upper level then it will go to upward and we could have say that the bull market is coming. So, as the market now come to the below and become more volatile let it become stable and see which direction it breaks. But you can buy now also.
It is obvious that all the crypto coins are very unpredictable due to very un-regulated market and the price is determined by the market force. But, some of the coin which are Top-10 or 20 are a little less volatile than the others. If you compare the Bitcoin and Ether then the decline is less because other coins are already declined more than 30 or 50 times. And, I suggest you to invest in BNT which is very less volatile to the market force.
This is the point in every mind that everybody in afraid of loss and also for the safety of their coin. If you are holding your coin then must enable 2-factor authentication and also enable for your e-mail. But, If you are to hold for longer then buy a Ledger or Trezor the most secure hardware wallet and transfer all your coin to this wallet. Here are for lifetime safety.
I haven't heard about this NEXO coin but I think this could be another giant in the market which is now traded at nearly $0.10 in the exchanges. And the rank according to the coinmarketcap is 65. So, investing in this coin won't be worthless.
The main reason behind the crypto falling at a unusual rate is that there no particular body that will regulate the crypto segment. All the crypto coins are traded according to the market supply and demand. So, do not worry about the market crash just invest in some good or the top 10 coin which will definitely make you millionaire in the next bull run.
Almost all of the coins are now worth buying. First of all you should go for TRON and VeChain. But there are many others are there also which need to enter into your portfolio for the year of coming. Dim Coin is another giant which is created on NEM platform and has the more potential after the development of the HYBSE in this December. So, invest in Dimcoin also. Others are, Datum, HVN, BBK etc.
You can buy NEO at 7.71$ per coin but do not invest all money in this coin now because it will drop more and may be decline to it's floor price. It is possible that it comes to price level of $2 and then if market persist in further crash then the decline will be more and possible the price will come to below $1.
The best competitor of the Ethereum is for now is EOS and TRON. But, there are many others are also in the market which may evolve a strong competitor of the Ethereum and these are BNT, IOTA, ICX, Qtum, VeChain and many other also.
No there is no late for the investment in cryptocurrency but there is getting more and more opportunity day by day as the price is dropping towards the very ground level. The Ethereum is already near to $150 and Bitcoin in $4000. Invest now 20% of your fund and wait for the further decline. If market revive then invest your 100% of funds.
In the crypto field there is one single strategy or any separate study of books available that can provide exact prediction of the price for investing. So, you should only believe in your own mind and do your own math before investing. My suggestion is that always follow the direction of the price and the project behind the any token. Evaluate the project carefully then after put your money in any token.
This is obvious that who have purchased the ETH at higher price or the last boom period for them it is a disappointment situation. But they need to hold for the next boom. In the other hand if you see as a new investor then it is a buying opportunity because the ETH price has in very lower price.
