I also recommended Ethereum below 8,00 USD. Now this magic altcoin costs 250 USD - a gain of more than 3000%!
The cryptomania is upon us and the world of money and banking is facing a huge shift. Cryptocurrencies might indeed break up the corruptive and unjust paper money system ruled by a small elite of banksters. As I have stated many times the blockchain has been a huge technology breakthrough and I am very sure we will use some form of crypto money in the future. Which one of the now 700 available cryptocurrencies will be the winner is unknown and pure speculation. Most of them will go to zero.
Regarding Bitcoins I think you should continue to hold them. I personally have sold all my Bitcoins two weeks ago but do regret it already though I avoided the sharp pullback towards 1,800 USD but did not manage to open the full position again. So you can learn from that and just continue to let your winnings run. There are no technical signs that the rally has already topped. I recommend to move your stopp towards the recent low at 1,800 USD and secure a massive 380% gain.
