My portfolio is almost back to its all time high.
2018 was a bad year for this asset but we are back in believer territory again.
I think 20k is likely but I predicted that by end of 2018 and was Very wrong then.

Anyway some believe 100k is likely this year.

Get a little ... (say 1 tenth of a bitcoin) or 10,000,000 Satoshis and enjoy the ride. For a £1,000. (Grand)
