the purpose of bitcoin as an investment is to hold it and wait longer to have a good value of it.
No, buddy. Bitcoin can be used as an asset and as a currency it depends on each individual point of view but if Bitcoin is only used as an asset it will never the mainstream of payment, it will never the mainstream adoption and it will never achieve its purpose cause it was created to serve as an alternative currency to fix the problem (inflation) the government couldn't fix through fiat currency
