So I've seen a couple of these posts before, Where people ask's for suggestions on which single altcoin to put X amount of money into, with the hopes of it making them millionaires. Thought i'd try doing the same thing, buuut seeing as I Don't really feel like putting all of my trust into one coin, I thought i'd Do it with 5 coins.
The problem is that everyone will give you different answers depending on their own perspective, and you have no way to determine which is good advice and which is bad. The most important thing is always do your own research, especially if you're putting in a large amount. I have my personal favourites, but you need to ensure there is a degree of safety to your investments... so for this reason I would always say have a fairly big percentage in bitcoin, then the rest have a lot in higher cap alts and then smaller amounts in more speculative lower cap coins.
