Rather if you did the same with bitcoin you might have had better outcomes.

However I must clarify one thing - any top coin on CMC or CG list can be a profitable coin if you get in at a low price. Possible that your buying price was much higher.

So instead of diversifying the number of assets, you should diversify the positions of the same coin. Buy the same at lower price and wait for the price to rise so you can sell.

You can also buy Bitcoin, but since your reserve money might be low at this point I would not suggest it as the first step. This can be done when you get your next salary. Please do keep an eye on charts and buy accordingly at low price, otherwise don't buy.
