You have $1500 and you want to make a crypto portfolio with this amount. So, my suggestion would be first you should buy the Ethereum because this is the next boom in the market. Again you should allocate some crypto which are in top 200 and in high volume like Datum, CAPP, Enjin Coin, PundiX etc.
Yeah, you think the same as me! You should buy ETH right now but do not all-in. You have to allocate your capital to invest in different coins. ETH has a great chance to pump as this time. Furthermore, ETH is the second biggest coin in the market, investing in it doesn't have a lot of risk. However, I suggest you to invest in top 10 coins in CMC only, top 200 is too wide!
