Lately, we know the market price of altcoin weakened. Whether or not the purchasing power decreases. Please explain to me what makes you interested in altcoins? And give me an explanation of what you will do to overcome things when altcoin the price dumps?
You need to learn to decide. People, who look for advices all the time do not manage to get rich, because they just copy, without any sign of understanding. You need to learn how to understand the market and how to predict the changes. In other case, you will loose a lot.
