If you feel like STEEM will be harder to earn in the future why do you feel that the price will go up? People aren't going to get excited about dumping $10,000 into something to try to earn an extra $10 from it in a month when they could have just bought Litecoin or Bitcoin and just watched the price appreciate more.

Personally I don't think it makes sense to keep buying STEEM because it can't even keep up with Dogecoin or Bitcoin Gold.

Even with the fact you are able to earn from it you can't earn fast enough to even make up the difference and you spent a ton of time.
