by seeing the price of BTC rising very high over its ATH, then it makes me jealous, because the price of Ethereum hasn't risen as high as the price of BTC, because for now i'm only invest in Ethereum, but at least i'm happy if the price of BTC has risen very high, so this proves to people that investing in cryptocurrency can get a big profit and of course it will make many people start to investing in cryptocurrency, so that in the future this will make the market cap and the price of cryptocurrency will increase higher than now (including the price of Ethereum).
Looking at the growth of bitcoin in terms of valuation if you think that the rest of the cryptocurrencies will rally then you will end up regretting as there are many evidence in the market and you cannot trust the entire market. The top coins can be trusted and it will give you the profit if you had the opportunity to invest when the price was really low, right now i will not dare to invest in anything and i will sit out waiting for a correction to invest again and in the meantime looking for the right opportunity to book my profit.
