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.
