If you're going to make a long term investment on this or any other coin, for that matter, you'd probably be better off making decisions on your own. Most responses you'd get here are self motivated, including mine I admit.

One thing to note: if any alt sets off with the mission to "dethrone" Bitcoin, they should work first on adoption and utility. Not price, not tech, not even fast confirmations or zero fees. Almost all alts are supposedly superior to Bitcoin's tech, but that's not the only thing or even the main thing that will make people switch.

So far, no alt can match the Bitcoin community's support. Got a problem with tx? Ask and knowledgeable people help. Developers at BTC are also the very best. You get a secure, tested, solid and mature coin with Bitcoin. Got a problem with an alt tx? wallet? Try see how many people help, and how many give useful advice.
