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.
This is not meaningless, but not effective especially if the coin has a very low price. Therefore, it is better to collect more coins at a lower price than to take 1 bitcoin and expect a miracle.
