I have been participating in the crypto world for many years as a miner and more recently as an investor / speculator. I believe we are now on the edge of a big crypto shake up like what happened to the dot com bubble. When this happens you wil see both winners and loosers in this world. I believe Bitcoin will still be on top although not as high as I want because of the Bitcoin Cash hard fork. Then maybe Litecoin because of its recent stability. And my long shot would be Dogecoin. To play it safe I would buy a little Litecoin just to be in if it makes a move. Not so much that it would financially hurt you if you lost it all but enough to make you supper happy if it goes to the moon. With Dogecoin I would put litterally lunch money into it for the same reasons. As for Bitcoin, At this point in time I see it as a rocket that already took off. You can be my guest and chase price but if it crashes it could hurt your wallet. Investing now in bitcoin now takes a person with a lot of guts and that is not how I invest. As for Etherium I use to like it until I found out who backs it. Then I turned the other way. EOS is getting more and more media coverage and after reading the licensing agreement I really don't like it.
So to wrap this up. If you are interested in crypto look at Litecoin (investing) and Dogecoin (like a lottery ticket). Put as much in as you can afford but don't put so much in that you will be living in a box in an alley if it crashes. Stay away from Etherium and EOS and enjoy the ride. :)
