its not a good idea to go all in on 1 thing no matter how good it looks or how much potential it can have. its always better to diversify. Right now my portfolio is 50% BTC, 25%eth, and 25% XCR. I dont have that much money but I am looking for Altcoins with high potential to put money into.
True. All of the altcoins today may seem just a cents ( eth is quiet expensive too) and in the near future they're prices will bloom because they are created right next to btc and they are the one who will serve as a pioneer coins in the development age of cryptocurrencies.
Bitcoin should be used as an investment vehicle to diversify and should not be used as a sole source of saving. You should only every take risk with currency that you can afford to loose. I personally invest 80% bitcoin, 20% altcoins both at ICO stage and currently available.
My method is to avoid buying other alts ( which because I don't have much cash ) every ICO and signature campaign im gonna join I think I will save at least 30% of the coins that I earned for future purposes because the price might increase muktitimes in a couple of years especially when it is in the exchanger.
