gold has reached the point of maximum dude
Yes, bitcoin is really great if you are planning to invest for a long term investment, you just need to buy bitcoin today. And hold it for a long time.
Put it to your cold storage wallet and wait for the years to come for you to earn.
If you can really afford to hold it for next 10 years then I think it can be the best investment, just imagine if price reaches to $10k or higher in future, the profits that you are gonna earn from it.
What you are saying can be true, but there are many people who will not hold their coins that long and no one have patience to hold till it reaches to $10k price.
