Keeping Risk Reward in mind is in general a good idea.
But buying up 10% is overkill, you can't drop that amount without causing the price to fall.
Well its a "i want to be ultra rich fantasy", but be more realistic.
0.1-1 % is enough and easier to sell.
A big bag holder can controll the market price with his huge volume.
If you unload your bag to fast and or in to large chunks you can start a downtrend.
So the only way to sell such large amounts is in small chunks over 1-2 years.
So you must be really patient, and stress resistant.
In these 2 years the value of your bag can everytime fall or drop to zero.
How many different coins did you buy?
