Holding them or trading them with altcoins on trading sites like ecoin.eu. I trade my btc for LTC and wait for it to rise up but its quite bad for LTC nowadays.
Two years ago, I got some hefty profits by converting my BTC to LTC, but I'll not recommend it to anyone. In January 2013, the exchange rate was going at 1
BTC = 400 LTC. I converted one of my coins to LTC. Then a few months later, the exchange rate climbed to 1
BTC = 40 LTC. I got almost 10x profit, but lost most of it later in an investment scam.
If you gain 10 times of your investment that is called good investing.
But if you lose then all then that is a bad thing to do.
In Bitcoin world you need to call it a good investment when you get your initial money back and they still pay. 10 times profit? Where is that in bitcoin area? There are maybe a handful investments against hundreds where investors lost all or practically all.
put 7-8 bitcoin in a secure cold wallet and invest like 2 bitcoin in trading. i myself am doing altcoin trading which is pretty good if you know how to profit (i am still learning though) but the profit can be good.
take an small amount like <1 BTC and gamble for fun
2 Bitcoins for trading is way too much for the start. Since you will lose them with practically 100% security. A newbie will not win, its a hard learning curve.
Historically, the first generation of a given innovation ultimately is not the one that persists.
Nah... i think there are a lot innovations that got their market share so big that no competitor could do anything. And bitcoin got already a lot of competition, not one had a chance.
And really... i dont can imagine a coin that is so good that everyone would go there and leave bitcoin. Maybe bitcoin gets renamed to bitcoin-xt or something, which i would hate because for sure it will be connected to a company, and not being only a free currency, but bitcoin will remain the strong one.
Though if you want to see it that way... at one point in time bitcoin will be replaced with something way better. But thats far in the future i think.
