I think that one should do quite a comprehensive study before investing as there are so many good projects and not so much money. My advice is that you should invest in coins that are listed on great exchanges, as they do quite a bit of research before signing a coin.
That's a good suggestion - the region you live in - might have a different investing opportunities.
Which people form different countries might not be well aware - do a bit of research and make a move. Once you make a decision - stick to it!
