The YEAR 2020 this is what BITCOIN and ETHEREUM will be WORTH!

Check out these calculations:
How much could one Bitcoin be worth?

In 2020, there will be ~18,375,000 BTC in circulation. $1,137,500,000,000 divided by 18,375,000 = $61,900 per coin, ~+2,200% from today.

How much could one Ether be worth?

This is a little harder to calculate due to the somewhat unknown supply of Ether in the future, how Proof-of-Stake might change new Ether issuance, and the impact that the Ice Age will have on time between new ETH issuance.

The original 2014 issuance model, stated a projection of ~162M ETH in circulation in 2020, however /u/manly_ ( A reddit poster) pointed out that Vitalik has said it would be closer to 100M, so for our rough math we’ll use 100M ETH.
$1,137,500,000,000 divided by 100,000,000 = $11,375 per coin, ~+4,000% from today.
In conclusiion:
If BTC and ETH represent 33% of the total market opportunity each, then each would have a total value of $1.502 trillion.

BTC would be worth $81,742 ~+2,900% from today.

ETH would be worth $15,020 ~+5,300% from today.

Stick your coins in a wallet and carry on with life. Check it every few months and don't PANIC! Add a few other cryptocurrency's like Ripple, DASH ,LITECOIN...thats my 3 cents worth!
