If you don't know what's happening on August 1st, stop here, go read about Bitcoin Civil War. In one sentences, there might be a Bitcoin split into two coins and know one knows what will happen !
We are already seeing the uncertainty and its effect on the prices. Here are my reasons why you should buy as many as Ethereal today !
Scenario 1: Bitcoin splits and prices crashes: This will put bitcoin years behind in terms of certainty and market cap. There is no guarantee that the prices recover ever and become the market cap leader.
Plus Bitcoin was the first cryptocurrency invented with a lot of flaws. Ethereum brought a lot more advancement and speed and is already gaining a big adoption. In case of a crash, investors might put their trust and money in the next logical and safe cryptocurrency which is Ethereum.
Scenario 2: Split doesn't happen and Bitcoin moves with the new and developed, it will start to go up again and when Bitcoin price goes up 1x, altcoin prices go up 1.5x.
The smartest move is to cash out to $$$ and wait for a few weeks and make a reactive decision with respect to your cryptocurrency positions.
Besides all the current context, the prices are falling now and the best time to buy is always when everyone else is selling on panic. Keep buying on crashes.
