I haven't sold anything to get more Bitcoin, but I have been hustling hard by budgeting and cutting back on unnecessary expenses. I have also been putting in extra work hours and taking on side gigs to earn more cash to invest in Bitcoin. I see Bitcoin as just one part of my overall investment strategy. While Bitcoin can be a great investment, it is still a relatively new and volatile asset. I think it is always wise to spread your risk across multiple investments.
You sold your fee time and leisure to buy Bitcoin
.
Anyway, I sold my altcoins to buy Bitcoin. Even though they have the possibility to give more profit, but the time when it will explode is unknown. Aside from that one wrong move from those altcoin developer will render them worthless. So I'd rather have a more liquid cryptocurrency than a shot to the moon altcoins.
