Buy in little by little with perhaps $50 per week until you reach the maximum you feel comfortable with. You will not gain so much, but it will also soften the price drops.
of course these steps also adjust to market conditions that are running, if the price is not allow us to buy, better not forced to buy it
I dont understand what you are trying to say - investments are based on people's emotions and current financial conditions and not always market conditions. Market does imply what people will do but this is not hard and fast.
I would like to start from $50,000 now because i have already some of the bitcoin and this is not bad to wait for the future i want to start from this amount for now and if i have some more money in the future i will invest in some altcoin as well but i want to start from this little amount So it may clear to me about the profit and other volatility of this currency.
For me, this option is even worse than choosing 50 dollars first to make the investment. The newbie must not risk with the huge sums of money until he feels he knows almost everything about the market of the cryptocurrency.
I believe OP is no longer a newbie after reading all the posts in this thread. As for 50$ buying one or two good altcoins is enough. Bigger capitals are needed for good and more profitable investments. Bitcoin purchase at current price may not be worthy if you buy small amounts.
