Are you still holding your bitcoins?

If you still have patience, I think there's no harm to keep holding them. Bitcoin is bitcoin. What I mean here is, it could go up again to more than $20K, there's no doubt about it. Only the question is... when will it happen again

We should aim for a bigger target, IMO. The level that you are talking about ($20,000 per coin) was already achieved once. The next target should be $50,000 per coin, or at least $25,000 per coin.
