I'm pretty new to crypto, started messing around with it in January. I got a lucky hit and sold off for a gain of $300~ worth of bitcoin. Now, I'm trying to do a bit of research - a large part of that is which exchanges are better to use, for reliability and fees etc.

I've read a little bit about Segwit, and believe that's a big part of why BTC transaction fees have dropped from the $20 mark that they were at in December, but have also heard that some exchanges haven't implemented it.

Sorry if all of this sounds pretty noobish, currently I'm planning on taking the $300 gain and exchanging into fiat and/or altcoin(s). Also, what's the best wallet out there, currently? Not for long term holding, if I do go into a long term hold, I figure I'll do either a hardware or paper wallet.

Getting into crypto has been pretty fun so far, I'm enjoying messing around with it more than the gains from it, honestly

Thanks for any advice!
