I have some bitcoins and found a secure way to keep them. What do I do with them now?
Keep them secure and safe. Open them after 3 to 5 years and you will see how huge is your profit. And if you want to believe that Bitcoin will be 1m dollar a piece in 5 to 10 years then keep it and wait for that time. Who knows the person might be correct.
I think it's been a long time. I think we should use it to generate quick profits, waiting just to make us feel depressed.
You may wish to make quick profits, however, it is always accompanied by danger. For business people, they always focus on safety, so some people choose to invest in bitcoin and they wait a very long time. You may feel depressed for that, but safety is always on the rise.
Speaking in terms of safety, there is no guarantee yet that the price of Bitcoin would remain on the increase. As with every other financial asset out there, price do reverse from time to time and with the speculative nature of Bitcoin, one cannot not say for sure how far price can go the other way, before reversing.
What is safe is always to diversify your investment and keep tabs with fundamentals in the ecosystem, 3 - 5 years of HODL is no guarantee still, because price could drop in the 5th year after advancing in the previous years!
