The BTC has made history today and broke its all time high record. It is currently trading around $ 20500 to 20600. BTC Dominance Index is around 65% which is very High. I personally think that it is the Right time to take entry in Good Alt coins ( Ranking from 2 to 20 on coinmarketcap). I believe that History of 2017 will be repeated soon. We will soon witness Huge rally in Alts. It should happen when BTC will stabilize around current levels and BTC dominance Index comes down to below 60%.
In my opinion, this is not the best time to buy altcoins. If you check now, altcoins are mooning. It is very wrong to jump into trades. But if you are in for long term holds, you can buy some solid coins. Check CMC for solid gems and don't forget to make your research.My opinion!
Though Alts market has done so well during the past 30 days but still there are many good coins like LTC, ADA have not surpassed their All time high record. They still have upside and I think in coming days/week we may see good rally in these coins including BNB. BNB has already broken its all time high record and still in Bullish trend. This token has l Huge intrinsic value because of its strong use case. I will not be surprised if it hits $100 during 2020.
