The thing is, it all depends on how much money you have left over to invest in bitcoin because if you really believe in bitcoin i think that getting a lot of bitcoin is a pretty good option. Because the value of the bitcoin will keep rising.
Most people dont have much money as "left over" after calculating their savings and expenses. The ones who invest in crypto either have a lot of money at hand or are willing to convert their majority of savings into crypto for future returns. Simply believing the price rise in bitcoin does not affect the market much. You need to cash out money and then cash in during the pump cycles.
I am really willing to invest big into bitcoin
Dont invest "big". Invest what you can afford to lose. Dont end up getting into a debt to invest in bitcoin.
