That would depend on what you consider to be adoption. Right now people are holding cryptos not for adoption but for speculation. Really the only cryptos I think will be useable as currencies are steem (and sbd) litecoin and bch. Bitcoin can no longer feasibly be used as a currency. It's hard to come to terms with, but I think there is foul play with bitcoin. Maybe it's wallstreet gaming it, maybe it's the globalists at AXA controlling Blockstream. I'm not one to say with certainty. I feel like right now may be a mania to get rich rather than to change our money system (for the majority of crypto users). I believe in adoption but it makes it tough with all these people hyping it up to get rich. And don't even get me started with all the different ponzi schemes!
