If you lack knowledge about Bitcoin, you won't be able to take part in those Bitcoin early day's faucet, and being able to exchange it at that period between 2009-2010 as mentioned, but the thing is that we have to under that Bitcoin at that earliest stage lack support and those that got it then thought it won't amount to anything.
But now the reality proven that Bitcoin is worth more than all other assets as far as investment is concerned, and for that we have to agree with that factors that said what you don't know you probably throw it to the dogs, so don't blame yourself too much and good that you are here now and learnt about it on time and hope you will make the change now.
There’s no room for regrets, but regrets are always valid. Don’t get too serious about it losing your bitcoin in the early years, you still have all the chances to accumulate more of it if you start moving now and make consistent buys or follow DCA. And also, you weren’t alone on that case, a lot have lost their bitcoin because they have only less knowledge about bitcoin before. So never dwell with it anymore, but focus now on your goal and start putting some actions on your plans to make them realized later on.
