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.
There is no fix amount in this field of business, we should bear that in our mind mate. Because of the volatility whether Bitcoin or crypto, we cannot say what will happen to its price value in the market. That's most of the traders they implement day trade to get profit. And it is true that We must be wise before investing into something so that our money will turn into nothing.
