Dear All,
one of my friends have 45 BTC in his pocket.(which was bought 5 years ago).
Need expertise advice how to use them effectively??
I would advise to fix his profit. Your friend had already done a great move. So why not to tranfer 15-20 BTC in fiat. That money could be invested in some more conservative assets tham cryptocurrency like stock market of real estate. Another 20-25 BTC should remain in crypto.
