I recently purchased 0.0045 Bitcoins which is still present in my trust wallet I believe with me owning a fraction of the worlds Bitcoin although a very tiny fraction in practical I am now a crypto currency investor in essence a Bitcoin investor
Kudos, OP. Don't weigh what you've as a mere fraction. That 0.0045 is $135 in today's worth. So, you see? It's not really that small. I bet you, you can still find veteran members who don't even have a single satoshi they're hodling. They buy or earn and then convert into fiat almost immediately they've it. Just continue buying.
