Totally agree it is a long-term investment! What matters is HOW LONG? This is the vital point especially for those beginners, who are so afraid they would lose money, care for instant lose or win, and would totally panic when loss occur. Cryptocurrency exchanges, more so than stock exchanges, are vulnerable to being hacked and becoming targets of other criminal activity. Security breaches have led to sizable losses for investors who have had their digital currencies stolen, spurring many exchanges and third-party insurers to begin offering protection against hacks. Risks sometime is the thing cannot be taken by investors.
As for using profits made from Bitcoin to invest in other altcoins, I really don't think a newbie like me can pass this. Hahaha, Bitcoin hurts me once, which need time to remend, and I don't think to turn into another's hug would be a better way to recover.
