The movements of the whole year 2017 were mainly caused by the attention of mainstream media and speculants. It was in my eyes an abnormal fast upturn of nearly all well established cryptocurrencies. Now we have a market again with steady upmovements, which reflect the blockchain based developments.So my advice is:
1. Keep your money out of crypto, that is needed to pay your bills.
2. Think long and don't follow each little market movement. Keep your coins.
3. Build up your longterm portfolio with some well established cryptocurrencies.
4. Keep your eyes open for innovative blockchain based projects.
This is the best analysis or better still explanation of what caused the Bull run. But don't you think it's still possible now smart money, market makers and so on.
