Buying bitcoins is always a great idea, but I suggest to enter the market with this system: 50% in bitcoin, 20 to 30% in Etherium, another 20% in other strong Althing, and the remaining money is better to invest in the ICO and other risky operations, but to maximize profits.
That's a good idea. Don't focus on investing in bitcoin only, but rather invest also in altcoins. Ethereum has a potential to grow same with other altcoins. As of now, we don't see any recovery with bitcoin and altcoin price in the market, but if the right time comes, then for sure you'll going to earn huge profit when the bear market ends.
