So I can only invest small and have put some funds in some cheaper coins. Then there are these more expencive ones. Is there a point of owning 1 or 2 of each or is there just no chance to make any significant profit that way? Sorry if this is a really stupid question, I'm a noob.
The coins with higher value provide more stability than the coins with low value. Definitely you can earn significant profit by investing in coins such as NEO and LTC, because these are less volatile and show steady growth over time. Moreover these coins are secure to invest in.
Though you wont be able to make large profit like you could make in coins with less value and low market cap, still you will get steady returns and your investment will be secure and less volatile to the market.
