I think Bitcoin/Cryptocurrency especially the many Altcoins in the market right now are available on a wide range of exchanges and it's pretty easy to get on those exchanges to trade - you can get a digital wallet to store your coins on many sites, including on exchanges and more importantly, there have been a lot of upcoming blockchain projects that offer their own digital wallets as well. Additionally, there are new crypto projects and their corresponding tokens appearing every day - and these projects offer to solve a problem seen in for example, traditional payment processes, or for users like us to bypass intermediaries and gain access to a product or service directly without paying extra fees. In general I think once you get past the initial stage of trying to figure out how to trade with Bitcoin and cryptocurrency, and also gain more insight into the many projects and their tokens, it becomes much easier! The only downside to it is depositing and withdrawing fiat from the cryptocurrency you have - but I've also seen great projects that provide debit cards along with their wallets so you can actually directly convert and use the crypto you have at physical stores to pay for items, so if you're talking about user friendly in this sense, that it's definitely becoming more user friendly!
