E good say helpful topics about Bitcoin dey dey thought of but if you ask me, this wan no follow, since nah something we don hear about over and over again.
Person wey say him dey go farm and no carry the necessary tools never ready to get results and nah the same thing with investment. Many people dey wey wan make profit but no get the patience level to see am out and as the Op note say a long term investment supposed reach like 8-10 years but what if people dey wey want to dey see profits quickly, nah there you suppose advice them to do DCA as that method nah still investment, only say nah short term but e still help to present them with options since them fit feel say as long as them no reach that period of time, them no invest.
