For peace of mind buy and hodl for a long term atleast for two bull circles you will be sure that whatever price will be then you will be in profit. DCA method is recommendable for income earners, buy with a percentage of your income and hold for the long term.
One year long bull cycle dey enough too for investors to take advantage of their investment in bitcoin. Every bull cycle from when one end to when another one go start again dey take at least four years, and four years dey enough for person to hold bitcoin and then become profitable for person. If you hold for two bull long cycles, e no mean say e bad, e dey very okay and you stand at a better chance to earn more than the person wey sell after only one bull cycle. Bitcoin investment na long and profitable investment for us today, so if we really wan enjoy how Bitcoin dey, na to invest for the long term and then forget about troubling our minds on whether we go dey profitable on am or not/ whether we go face big loss the time wey we wan sell.
