I just bought tokens in Crypterium and Beluga Pay. (This is not an ad to them, so Google them yourself if you want.)
Instead, I want to highlight the difference between buying cryptos and buying into ICOs.
Are you a hoarder or an investor? if you are buying cryptos hoping they will (continue to) go up in value, then you are a hoarder, and that's okay. But if you want to actively invest in the blockchain new industry, then you will be better off participating in ICOs.
Buying cryptos is like being a forex trader (hoarder in this case.) Buying ICOs is like being a stock investor.
See, startups that sell tokens in ICOs (to fund themselves) are actually planning to sell a product (or service) on the back of the blockchain. Instead of asking for USD or EUR, they ask for cryptos and give you their tokens in exchange. Once their services go live, the value of their tokens will go up or down depending on the success of their activities.
As the crypto market matures, there will be less and less growth opportunities out there if you only focus on the value of cryptocurrencies. But the growth potential of companies using the blockchain will never dry out. They are immune to the price of altcoins - they only use them to sell tokens.
Just think about the potential growth of companies in the stock market. They don't care (much) about the price of fiat currencies (USD, EUR, etc). They just need to fund themselves when they do an IPO. After that, the value of their stock will follow their success as a company.
Buying cryptos was fun for me for a while. Now I'm buying ICOs.
