To me BTC is an investment. It has huge potential for capital growth and a currency which does not suffer from inflation and manipulation by central banks.
Central banks cannot regulate bitcoin but they can do that with exchanges and other businesses that accepts bitcoin.
We have to be knowledgeable with the law as for sure it will be regulated soon as the demand increases, though they cannot see
how much we are holding and what are our transactions but they can require us to submit a report.
Just make sure when you hold or invest you also educate yourself at the same time so your money will not be compromise.
