in relation to other reptiles you've been doing so far, the answer is a definite NO.

reasons:
1) takes ages to sexually mature
2) takes more space
3) much more setup requirement (water/land area, basking light)
4) more overhead costs (electricity, water bills, high food intake)
5) niche market
6) some of those most profitable stuff (morphs aside) are things that can't be obtained or traded without legal whatnots.

if you ask nonono, of course his answer will be YES. but he's different. he feeds albino redfoot corns, puts albino sulcata under direct midday sun and answers questions like ah beng, but he can still make sales LOLLLL
