Short term you can make a lot of money simply by following a particular project's developments and staying ahead of the market. Long term... good luck.
Why? Because 99% of crypto doesn't have a use case that's ALSO associated with real revenue. Of the 100s of crypto currently in existence, where do you see them in 5 years?
It's one thing to go from an idea. So many of these projects are phenomenal ideas. It's a huge leap to then go from an idea to a usable product/service though. If you are lucky enough to get to this stage then it's another huge step to adoption. Then you also have to consider if it's adoption in some small niche market versus more widespread/global.
Long term, I like Gamecredits/Mobilego and Incent. (Disclaimer: I'm invested heavily in GAME and will also be in MobileGo. Also invested in INCNT but to a lesser degree. My financial involvement and excitement likely impairs me from seeing potential downsides as well as I would otherwise. Please do you own homework on any investment).
It's incredibly easy RIGHT NOW to buy GAME with a credit card. You don't need to use some sketchy exchange. You don't have to wait on a bank transfer. You don't have to provide all of your personal information. You can go to their online wallet with your credit card in hand and have GAME in less than a minute.
They're about to also implement it on their platform. Gamers won't even be aware they're actually buying crypto when they make purchases. They have essentially bypassed educating the public on crypto and will be getting people to adopt it without even realizing it. It's not some obscure niche market their targeting either. Mobile gaming is a multibillion dollar industry and rapidly growing.
How many altcoins have relied on large ICOs to raise millions from strangers based on nothing more than some cool ideas and a flimsy road map? The team at GAME has been developing for years with their own money. That is somewhat of a rarity these days and I think says a lot about them.
They're doing so many other things that indicate to me that this has been well planned and I suspect it will also translate into good execution. I think the bonus for they're offering for using GAME in the MobileGo ICO is smart because it adds additional buy pressure for GAME. They haven't publically discussed it much, but they will also be involved with fantasy sports. Not directly, but through sites like SuperDT.

MobileGo is symbiotic with GAME. I think it has potential for many of the same reasons as GAME does as well as some other things. I think it's trajectory is a little longer, but I suspect even more promising.
Incent (INCNT) I think has some potential for widespread adoption too although I think a harder road than GAME does. The blockswap technology is cool. I like how they're using it to piggyback onto other ICOs (3% of Encryptotel ICO will go to buy INCT off the open market and 0.5% of MobileGo ICO will do the same). If they can continue to be involved in additional ICOs then this just adds more and more buy pressure on the market for INCNT. Not only that but the people in the Encryptotel and MobileGo ICOs wont just be hearing about INCNT (some might not even know) but they'll physically own it. It's one thing for someone to see your crypto on coinmarketcap or mentioned on a forum and it's completely different for them to have it in their possession. They're simultaneously raising awareness and also adoption. This isn't even their main focus either!
Edgeless(EDG) was mentioned earlier. I like the idea a lot. It's a pass for me though. I got into crypto originally through sportsbetting/online gambling. I think crypto has a bright future in in this arena. I haven't seen enough from EDG at this point to make me think they can pull it off.
