Bitcoin price is rising up in rocket speed and penny-pinching mind is always yelling that hold.. hold and hold your Bitcoins. Don't convert to fiat or spend them. But, there's a big risk...what to do?. This is a question somebody asked me today.
I didn't answer at him, but, thought deeply about that and got the following mind.
If you've 10BTC convert 5BTC into fiat and wait until the remainder is reaching to 10BTC and do the same again.
Is this a good advice?
2017 Bitcoin is a bubble and no one can claim the 2018 bubble does not come back? But there will not be any bubbles that Bitcoin will add value over time as a rule of thumb.
I do not think there is any good advice in this decision. Opportunities and risks are defined by themselves, while objective factors play only a small role.
