I agree. 20% per year is good for everybody. But i would like to get 20% every year. I don`t sure that if i would by BTC today, i would get such percent. It`s cost is too high as for me.
20% per year is a dream percentage, most people fail to make 5% per year. Don't joke around these things with made up numbers. Most people don't even make 2% per year consistently.
And i know myself, i`ll sell when it would be x2-x3.
Then you are better to deal with altcoins, Bitcoin is not for selling.
First of all. Where i said that i get 20% every year? oO I want don`t equal i get.
Second. I don`t know where you get statistics, i don`t have information about 2% or 5%. For me normal profit 7-12% per year. For my country it is normal profit. It is without cryptocurrency, just fiat money.
Third. I can decide what cryptocurrency i would buy/sell myself. x2 in BTC for 3-4 years would be good profit for me. Altcoins that can give huge profit can scam easily. Big altcoins wouldn`t give x10-x20.
