So, when I started reading on this forum, I got curious about alt coins. So my questions is, what alt coins are a better investment? How to start investing (assuming I have 500 US dollars) on the altcoins that you suggested?
Since you said altcoins, and only looking at Top10, and excluding bgold because I don't really see any value in it, and I think it would never be there if it wasn't created from a bitcoin fork, I would say that Dash, Ethereum, and LTC, are good investments. I wouldn't forget Monero and IOTA as well, and although I would consider these two as more riskier, I wouldn't ignore them.
LTC and Dash will probably be the best choices to work as a payment method. Ethereum is the most reliable platform for investing in blockchain projects, and IOTA could be a better solution for micro-payments than ripple or stellar. Monero is good for privacy, and it will be around for a while as well.
