I think I can only invest $100 a month for the next year or two, would that be enough? I am worried about missing big bull market with halving and etf approval.
The point is to invest in as much bitcoin as you can afford and be ready in case of loss. because investing in bitcoin certainly has risks. So don't force yourself to buy as many Bitcoins as possible but are afraid of losing.
If you can only afford $100, stick to a strategy that you believe in by buying every month. If we talk about enough or not enough, of course buying Bitcoin doesn't feel like enough, because the more you buy, the better it will be when there is a bullish situation. This is the advantage of dca, even though we don't have a lot of money to buy bitcoin, we can buy bitcoin gradually and as much as we can so that when we accumulate a lot of bitcoin.
