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.
Completely agreed that this is not a fake bull run, Bitcoin is in possible bull run now but altcoins are not moving with much speed. I also agreed to the point that once there is good money from bitcoin it will get reinvested into altcoins, this has happened in the past as well. I remember late 2017 when Bitcoin rose from $1000 to $19000 in some months and there after altcoins started moving. I think history will repeat after 1 and 1/2 years, now Bitcoin is rising and after sometime we shall see growth in all altcoins.
