A good idea might to be purchase 1000 DASH ($1 million ish about 90 Bitcoin) You get proof of Stake and will get 2 DASH per week as interest, you so just easily sell of the interest received roughly $6000 a month
This would be a good investment with your huge holdings of bitcoin
Wow! I think Dash would be a good investment for OP as he has a lot of Bitcoin holdings. Free money from Dash's proof of stake would be a good way to earn huge passive income monthly. 8,000 BTC is not a joke if it's true I think you need to keep those coins safely because that means a lot of money and you can now retire from your job if you have and live like a boss with your love ones.
