Both are important but the money needs to come first, to me this is simple if you see a prediction that the next day is going to rain you take with you an umbrella to work, this is the same, we know that bitcoin will become huge so at first investors will put their money here before that happens, and then years or even decades later the adoption will come, something similar happened with the internet and almost every industry in the past.
both need money and i think we already have enough money, beside it bitcoin and cryptocurrency itself is money, lol. and you know what will makes cryptocurrency huge thing is its adoption, lol.
adoption can't just happen if people don't know about it, and we don't have any marketing department to teach people how to use bitcoin coz cryptocurrency is decentralized and not a company. it is all depends on its community
what had happened to some dot-com companies with their shares value was bigger than company value? they fell at dot-com crash. and now we face same situation, market crash, ICO hard to grow, new coins price free falling to the ground.
lets take eBay as example, it survived and grow after dot-com crash because it continue to expand the company, reaching new users, and then it's company become bigger and shares price rise again. now what would happen if more ebay shares investor come, instead more ebay user? that will only become another bubble
