I'm a total novice - sort of.
In 2013 I bought some Bitcoin through MTGox. I cannot recall how many, but not a huge amount (still would have been worth a small fortune today, but hey-ho) and some months later (2014) I sold them, but I think might have kept 2 or 3 back.
When I checked last - in 2016 I assumed/was told that if I had any they would have disappeared when MTGox went under. That was the last time I had any interest in Bitcoin.
By chance recently I found I still had my Bitcoin Core wallet on my iMac and opened it. That was two days ago and since then it has been synchronising and at present is 35pc progressed. Estimated time left fluctuates from 48 hours to - at present - 11 days. I have a couple of questions.
1/. Is there anyway of speeding this process up? (I have 60+Mps connection) 2/. Given my Bitcoin history is it possible what coins I may have, if any, are here? 3/. Given the last block time was late 2015, should i just stop the process, upgrade Bitcoin Core (if possible) and start again?
Many thanks for any help/advice
