As per my experience , this is not fake bull run. this will be bull run , but do not expect 50000$ per BTC. BTC double ,means from 4000$ to 8000$ went in a short time , last 2 month it drastically moved up.
Now BTC will pump , after wards all the money will go to the ALT coins, they will pump up soon too.

Do not invest without research , your money your dedication. AS per my research

Nano is good for investment.
I've read some analysis and for a bull run to exist, there should be a good amount of buy orders just below the current price but this rapid increase in price are not supported by strong buy walls. So, when the people stops buying or comes a huge sell wall, the price would again plummet largely to reach the previous base price.
