The ratio of the price of Ether and bitcoin is not the best now. But it must be taken into account that at the moment there are already a lot of competitors of Ether, which greatly pushed this coin off the market. Proceeding from this, the price of Ether in bitcoins cannot rise very much.
Don't forget most ICOs are based on the Ethereum Blockchain, so it is actually still relevant for now. and for this price, the gains far outweigh the risks tbh.
