Is buying ETH currently a good idea, or should I be going with Bitcoin?
Of course yes. If you buy ethereum now you will get big profit in future.
But you can invest in bitcoin too. Both coins are very good now but which is better? It depends about your budget
both of these coins are very good investments in the future. currently the market is down. use your assets by buying coins that are profiled. before you buy coins, analyze it first by reading a trusted source. Good luck!!
