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%.
I think this isn't perfect time to invest on ALtcoins yet, especially with low and medium capitalization Altcoins. With big Atcoins such as ETH, XRP, ADA,LTC...you can earn 20-30% profit but not be able to earn more at right now because the marketcap BTC dominance and the price of BTC are rising so strong, it shows that the money flow is focusing on BTC. Let's wait until the price of BTC goes sideway and the marketcap BTC dominance go down, this is really good time to invest to Altcoins
